One of the biggest health issues facing women in their childbearing years worldwide is polycystic ovarian syndrome, or PCOS. PCOS is a prevalent endocrine condition with well-known negative effects on metabolism, reproduction, and cardiovascular health that contribute to substantial morbidity. There are still many unanswered questions regarding the precise mechanisms by which PCOS arises, and research into the disorder’s nature is ongoing. This study aims to investigate this uncharted horizon of PCOS by analyzing association between serum Caspase-1, IL-10, and biochemical indices relative to insulin resistance (HOMA-IR), hyperandrogenism (FAI), dyslipidemia, and oxidative stress in our female population. It expands on the significance of inflammation and insulin resistance, together with dyslipidemia in the advancement and signs and symptoms of PCOS. The work’s preface highlights the goal of advancing medical science’s ability to treat patients with illnesses and makes the case that interdisciplinary cooperation between gynecology, endocrinology, and biochemistry improves patient care. Our objective is to identify potential strategies to lessen the effects of PCOS in order to enhance the results of its diagnostic, therapeutic, and preventative measures for the millions of women who are affected.

Chronic wounds, including diabetic foot ulcers and pressure sores, are becoming more prevalent due to aging populations and increased metabolic problems. These wounds often persist due to impaired healing, chronic inflammation, oxidative stress, and infections caused by multidrug-resistant pathogens, making conventional treatments—including antibiotics and antiseptics—largely inadequate. This creates an urgent need for advanced, biologically responsive therapies that can both combat infection and promote tissue regeneration. Probiotics have surfaced as a viable option owing to their capacity to regulate immune responses, impede pathogenic biofilms, and generate antibacterial and antioxidant metabolites. However, their clinical application is limited by poor viability, sensitivity to environmental conditions, and short retention at wound sites. Nanotechnology-based delivery systems address these limitations by protecting probiotics from degradation, enhancing site-specific delivery, and enabling controlled, stimuli-responsive release. Encapsulation techniques using materials like chitosan, PLGA, liposomes, nanogels, nanofibers, and microneedles have shown significant success in improving wound healing outcomes in preclinical and clinical models. This review summarizes the current landscape of chronic wound challenges and presents recent advances in probiotic-loaded nanotechnologies. It explores various nano-delivery systems, their mechanisms of action, biological effects, and therapeutic outcomes, highlighting the synergy between probiotics and nanocarriers as a novel, multifaceted strategy for managing chronic wounds.

Brown rice (Oryza nivara S.D.Sharma & Shastry) is a rice variety that belongs to the Graminae family. Brown rice contains vitamins A, B, C, Zn and B complex. Vitamin B1 is one type of vitamin that is not stable. Its stability is influenced by pH, temperature and processing. The purpose of this study was to determine the comparison of vitamin B1 levels in brown rice and cooked brown rice. The study began with a qualitative test of vitamin B1 using 10% Pb acetate and 6 N NaOH if a yellow color and brown precipitate formed after heating, the sample was positive for vitamin B1. Determination of vitamin B1 levels in brown rice and cooked brown rice by alkalimetric method using NaOH as a titer that has been standardized in advance with potassium biftalat 0.1 N. Data analysis using the Mann Whitney test is an alternative to the Independent T-test if the t-test requirements are not met. The Mann Whitney test is used to determine whether or not there is a difference between two independent samples. The results of the qualitative test of vitamin B1 in brown rice and cooked brown rice showed that the samples were positive for vitamin B1. The quantitative test results of vitamin B1 levels in brown rice and cooked brown rice obtained an average of 12.40 mg / kg and 4.96 mg / kg. Statistical test results, the significance value (p) = 0.043, where p < 0.05 means there is a significant difference in vitamin B1 levels in brown rice and cooked brown rice. The conclusion of this study is that vitamin B1 levels in brown rice are higher than vitamin B1 levels in cooked brown rice.

Objetivo: analisar o perfil pós-consumo dos medicamentos descartados pela comunidade universitária no coletor disponibilizado no Centro de Ciências da Saúde da Universidade Federal da Paraíba. Métodos: O projeto de extensão Descarta CIM instalou um coletor no Centro de Informações sobre Medicamentos - CIM do Departamento de Ciências Farmacêuticas e promoveu campanhas educativas em outros centros de ensino do Campus I. A partir disso, foi feita a pesagem e catalogação dos medicamentos descartados durante um período de 6 meses, seguida de análise detalhada do tipo de medicamento, categoria regulatória, classificação ATC (Anatomical Therapeutic Chemical), forma farmacêutica, tipo de embalagem e prazo de validade. Resultados: Os dados encontrados indicam que os medicamentos genéricos representam 42,5% do volume descartado, seguidos por medicamentos de referência (35,7%) e similares (21,7%). A análise da classificação ATC revela uma prevalência de medicamentos relacionados ao sistema digestivo e metabolismo, seguidos por sistema cardiovascular, sistema nervoso e músculo-esquelético. Observa-se uma alta porcentagem de medicamentos fora do prazo de validade (72,8%), levantando questões sobre a prática de automedicação e a necessidade de conscientização sobre o uso racional de medicamentos. Conclusão: O estudo demonstra algumas limitações, sobretudo quando não se pode determinar com exatidão se todos os medicamentos descartados foram efetivamente utilizados pela comunidade universitária. Contudo, a análise demonstrou que a promoção de campanhas educativas e a presença de coletores incentivam o descarte adequado de medicamentos e estimulam uma mudança de comportamento e a prática de ações de proteção ambiental.

<b>Background/Objectives:</b> Lipid-based formulations are widely used to enhance the oral bioavailability of poorly water-soluble drugs. However, for weakly basic drugs with higher solubility under acidic conditions, precipitation and recrystallisation after gastric emptying can compromise a formulation’s ability to maintain the drug in a solubilised, absorbable state. To address this, we evaluated an enteric coating strategy to preserve the biopharmaceutical performance of a silica-solidified lipid-based formulation. <b>Methods and Results:</b> The model weakly basic BCS Class IV drug, abiraterone acetate, was loaded into a lipid-based formulation and solidified using mesoporous silica nanoparticles. In an in vitro lipolysis model, introducing the formulation only after the onset of the intestinal phase led to lower precipitation and over 50% greater drug presence in the aqueous phase compared to a two-stage gastric–intestinal digestion. In an in vivo pharmacokinetic study in Sprague Dawley rats, the silica–lipid formulation (6 mg/kg), delivered in gelatine minicapsules enteric-coated with Eudragit L100-55, resulted in a 2.6-fold higher systemic exposure compared to the non-coated formulation (<i>p</i> < 0.0001). <b>Conclusions:</b> These findings support the use of enteric coating for lipid-based formulations and silica nanoparticles containing weakly basic drugs as a strategy to maintain formulation integrity until reaching the small intestine.

Introdução Este estudo analisou a participação social nas consultas públicas promovidas pela CONITEC (Comissão Nacional de Incorporação de Tecnologias no Sistema Único de Saúde) com o objetivo de promover a equidade no acesso a tecnologias em saúde. A pesquisa, realizada por meio de um formulário eletrônico durante junho e julho de 2023, buscou compreender a percepção da sociedade sobre as consultas públicas da CONITEC e propor melhorias na metodologia de Avaliação de Tecnologias em Saúde (ATS). Métodos Foram coletadas respostas de 650 participantes por meio de um questionário eletrônico. Os dados incluíram informações demográficas, níveis de conhecimento sobre a CONITEC e ATS, percepções sobre o impacto das ATS na qualidade da assistência no SUS, viabilidade da participação pública, confiança nas decisões governamentais e a importância da participação da população na formulação de políticas de saúde. Resultados A pesquisa revelou que a maioria dos respondentes estava na faixa etária de 26 a 45 anos, com predomínio de mulheres (69,2%). Cerca de 47,7% dos participantes não trabalhavam na área de saúde, enquanto 52,3% estavam envolvidos de alguma forma, com destaque para aqueles que trabalhavam em estabelecimentos de saúde (26,2%). A maioria dos entrevistados (64,6%) conhecia a CONITEC e seu papel na saúde pública, mas apenas 58,5% entendiam o que era ATS. A maioria acreditava que as ATS impactavam positivamente a qualidade da assistência no SUS (75,5%) e que sua participação nas consultas públicas era viável (80%). No entanto, uma parcela significativa (63,1%) não tinha confiança de que o governo utilizava as informações coletadas nas consultas para incorporar novas tecnologias. A participação da população nas políticas de saúde foi considerada importante por 76,9% dos entrevistados, embora apenas 60% tivessem participado de consultas públicas online, possivelmente devido à falta de conhecimento (76,9%) e confiança (15,4%) em sua capacidade de contribuir efetivamente.  Discussão e conclusões Os resultados destacam a necessidade de melhorias nas consultas públicas da CONITEC para aumentar a confiança da população e garantir que suas opiniões sejam consideradas. Uma sugestão apoiada por 67,7% dos participantes foi a criação de formulários específicos para diferentes doenças ou tecnologias. Essas conclusões ressaltam a importância de reformular a metodologia de ATS e promover uma participação efetiva da sociedade na tomada de decisões em saúde.

Creams are semisolid dosage forms widely used for pharmaceutical and cosmetic purposes due to their pleasant appearance, easy spreadability, and the possibility to deliver hydrophobic and hydrophilic active agents. The aim of the current study was to evaluate the impact of type and concentration of different oil phases on the mechanical and rheological properties of cosmetic creams. For this purpose, a series of blank and anti-age creams were prepared applying the hot homogenization method (9000 rpm for 5 minutes). The blank creams contained an emulsifying base (Neofin Nat 8% w/w) and varying types of lipid phase: 1) babassu oil (8% w/w), 2) Cannabis sativa (2% w/w) and Camelina sativa (6% w/w) oils, 3) babassu (6% w/w) and Cannabis sativa (2% w/w) oils, and 4) babassu (6% w/w) and Camelina sativa (2% w/w) oils. The anti-age creams contained additionally Jasminum sambac flower extract (5% w/w) and Аrgireline® solution (5% w/w). The spreading, mechanical, and rheological properties of the developed formulations were investigated. The anti-age cream based on babassu (6% w/w) and Camelina sativa (2% w/w) oils exhibited suitable textural and rheological characteristics that would facilitate its application onto skin and provide sufficient contact time to exert its beneficial effects.

This study aimed to elucidate the anti-inflammatory activity of <i>C. tinctorius</i> leaves by measuring inflammatory parameters such as nitric oxide (NO) production and mRNA expression of iNOS, interleukin-6 (IL-6), and IL-1β in lipopolysaccharide (LPS)-induced HaCaT cells. Further, the effect of <i>C. tinctorius</i> ethanol extract on the MAPKs/NF-κB signaling pathway was examined in HaCaT cells. The phytochemical profile of the ethanol extract of <i>C. tinctorius</i> leaves was determined using UPLC-QTOF-MS/MS. The results indicated that the ethanol extract of <i>C. tinctorius</i> effectively attenuated LPS-induced secretion of NO, IL-6, and IL-1β in HaCaT cells. Further, LPS-stimulated mRNA and protein expressions of iNOS were decreased by pre-treatment with <i>C. tinctorius</i> ethanol extract at the transcriptional level in HaCaT cells. Moreover, the ethanol extract of <i>C. tinctorius</i> suppressed NF-κB signaling in LPS-induced HaCaT cells. This suppression was mediated by MAPKs/NF-κB signaling, inhibiting the phosphorylation of p38 and p65 in HaCaT cells. However, there is no significant effect on the phosphorylation of JNK by the ethanol extract. The QTOF-MS/MS analysis revealed the identification of 27 components in the ethanol extract of <i>C. tinctorius</i> leaves. The data demonstrate that the ethanol extract of <i>C. tinctorius</i> leaves protects the LPS-induced HaCaT cells by inhibiting the expression of iNOS, IL-6, and IL-1β and suppressing the phosphorylation of the p38, p65, p-JNK via inactivation of MAPKs/NF-κB signaling pathway. These results demonstrate that <i>C. tinctorius</i> leaves may serve as a potential candidate to prevent inflammation-related diseases.

Nanotechnology applications have emerged as one of the most actively researched areas in recent years. As a result, substantial study into nanoparticulate lipidic systems and liposomes (LPs) has been conducted. Regardless of the advantages, various challenges involving traditional manufacturing processes have hampered their expansion. Here, the combination of microfluidic technology (MF) and 3D printing (3DP) digital light processing (DLP) was fruitfully investigated in the creation of novel, previously unexplored “diamond shaped” devices suitable for the production of LPs carrying lysozyme as model drug. Computer-aided design (CAD) software was used designing several MF devices with significantly multiple and diverse geometries. These were printed using a high-performance DLP 3DP, resulting in extremely high-resolution chips that were tested to optimize the experimental condition of MF-based LPs. Monodisperse narrow-sized lysozyme-loaded PEGylated LPs were produced using in-house devices. The developed formulations succumbed to stability tests to determine their consistency, and then an encapsulation efficacy (EE) study was performed, yielding good findings. The in vitro release study indicated that lysozyme-loaded LPs could release up to 93% of the encapsulated cargo within 72 h. Therefore, the proficiency of the association between MF and 3DP was demonstrated, revealing a potential growing synergy.

Background: There is a lack of coordination among various healthcare workers in a hospital which leads to an increase incidence of medical errors and patient sufferings. The various professionals in a hospital are not able to communicate effectively and neither they can understand each other’s roles and responsibilities. This is because they have not studied or learned together. For this reason, the concept of interprofessional (IP) education (IPE) is picking up which is when students from two or more professions learn together for better patient care. Aim and Objectives: The aim of the study was to find out the acceptance among 1st-year university students of IPE being introduced to them. Materials and Methods: Two hundred fifty 1st-year university students, belonging to various courses such as MBBS, BPT, B.Sc., and Diploma allied health sciences such as operation theatre, radiology, laboratory, biochemistry, and microbiology were brought together for a common lecture where they were explained the concepts of IPE and practice. They were divided into mix IP groups of five each and WhatsApp groups were formed and they were given assignments on the topic which they had to prepare online and present on the next date after 10 days in the class. The author joined as a facilitator in each group. Even a voluntary poster competition among these groups was held after 10 days. Results: The students were really enthusiastic and out of 50 groups formed, good interaction was visible in 45 of the groups. Twenty groups presented very highly made posters. More than 90% students gave positive feedback for this method of interactive learning and found themselves more comfortable in dealing with other course students. Conclusion: IPE is an innovative method of learning and if introduced early in the curriculum, can be highly accepted. [Natl J Physiol Pharm Pharmacol 2021; 11(3.000): 242-245]

Background: Recently a number of trials investigated the effect of N-acetylcysteine (NAC) administration on inflammatory markers and homocysteine (Hcy). However, their findings are controversial. The aim of this paper is to present a meta-analysis and give a review of all randomized controlled trials (RCTs) in order to determine the effects of NAC on inflammatory markers and Hcy. Methods: An electronic search was conducted using PubMed, Scopus, Cochrane Library, Google scholar and Web of Science databases from inception until April 2019. A study quality assessment was performed using the Jadad scale and heterogeneity between studies was statistically computed using Cochrane’s Q test and I-square (I2). Data were pooled using a random-effects model and weighted mean difference (WMD) was considered as the overall effect size. Results: Out of 1115 potential citations, 10 studies (reported 13 effect sizes for different parameters) met the inclusion criteria and were eligible for this meta-analysis. NAC supplementation resulted in a significant reduction in Hcy levels (WMD: -2.05; 95% CI: -3.73, -0.37). NAC administration did not affect C-reactive protein (CRP) levels (WMD: 0.06; 95% CI: -0.21, 0.34), tumor necrosis factor-α (TNF-α) levels (WMD: 0.07; 95% CI: -0.27, 0.40), and interleukin 6 (IL-6) (WMD: -0.23; 95% CI: -1.23, 0.77). Conclusions: It could be concluded that this meta-analysis of RCTs demonstrated that NAC administration to various patients significantly improved circulating Hcy, but did not affect CRP IL-6 and TNF-α levels.

Background and purpose: Excessive melanin production caused by overactive tyrosinase (TYR) enzyme results in several dermatological problems. The TYR inhibitor, derived from metabolite changes during fermentation, has been well recognized for pigmentation control. Experimental approach: This study is interested in alternative anti-melanogenic agents from bio-modified Riceberry rice through fermentation. Modified Riceberry rice extract (MRB) was evaluated for its cytotoxicity, melanin content, melanin excretion, and TYR activity in B16 cells. TYR and their melanogenesis-related molecules such as TYR-related proteins-1 and -2, and microphthalmia-associated transcription factor (MITF) were determined. The anti-melanogenic activity and toxicity were also tested using the embryonic zebrafish model. Furthermore, comprehensive genotoxicity testing was verified by cytokinesis-block micronucleus cytome assay. Findings/Results: The study found that non-cytotoxic concentrations of MRB at 20 and 40 mg/mL inhibited melanogenesis and melanin excretion by interfering B16 cell morphology. Cellular TYR enzymatic activity was also suppressed in the treated cells. The mRNA transcription and protein expression levels of TYR and MITF decreased by dose-dependent and time-dependent manners with MRB treatment. In the animal model, MRB was found to be safe and potent for melanogenesis-related TYR inhibition in embryonic zebrafish at 20 and 30 mg/mL. The toxicity of effective doses of MRB showed no genotoxicity and mutagenicity. Conclusion and implications: This study suggests that MRB has anti-melanogenesis potential through TYR and its-related protein inhibitions. MRB is also safe for applications and maybe a promising anti-melanogenic agent for hyperpigmentation control.
