Repurposing simvastatin in cancer treatment: an updated review on pharmacological and nanotechnological aspects.

Management of cancer is challenging due to non-targeting and high side effect issues. Drug repurposing is an innovative method for employing medications for other disease therapy in addition to their original use. Simvastatin, a 3-hydroxy-3-methylglutaryl coenzyme-A reductase inhibitor, is a lipid-lowering drug that is being studied for the treatment of cancer in various in vitro and in vivo models. Nanotechnology offers a potential platform for incorporation of drugs with enhanced pharmaceutical (solubility, release characteristics, stability, etc.) and biological characteristics (targeting, pharmacokinetic, pharmacodynamic). Utilizing a variety of resources such as Scopus, Springer, Web of Science, Elsevier, Bentham Science, Taylor & Francis, and PubMed, a thorough literature search was carried out by looking through electronic records published between 2003 and 2024. The keywords used were simvastatin, drug repurposing, anti-cancer simvastatin, pharmaceutical properties of simvastatin, simvastatin nanoformulations, simvastatin patents, clinical trials, etc. Numerous articles were looked for, filtered, checked out, and incorporated. Pure simvastatin has been researched as a repurposed medication for the treatment of cancer in several in vitro and in vivo models, such as carcinoma of the lung, colon, liver, prostate, breast, and skin. Simvastatin also incorporated into different nanocarriers (nanosuspensions, microparticles/nanoparticles, liposomes, and nanostructured lipid carriers) and showed improvement in solubility, bioavailability, drug loading, release kinetics, and targeting. Clinical trial and patent reports suggest potential of simvastatin in cancer therapy. The preclinical studies of pure simvastatin in in vitro and in vivo models showed the potential for its ability to inhibit cancer cell growth and further incorporation into nanoformulations strengthened its preclinical and pharmaceutical characteristics.

Rhodamine B for Probing the Effects of Modifications in Cetrimonium Bromide Counter-anions by Transition Metals on CTAB/Butanol/n-hexane/water Microemulsion.

Dye solubilization in microemulsion based on Cetyltrimethylammonium bromide (CTAB) and its modified forms (counter-anions based upon Zn2+, Cu2+ and Fe3+) is comparatively innovative and not explored in existing literature. Here, surfactant with modified counterions (SMCs) were used to study the effects of metal chlorides (ZnCl2, CuCl2 and FeCl3) modifications on the comparative solubilization of Rhodamine-B (RB) by Cetyltrimethylammonium bromide (CTAB) and its modified forms. The solubility of RB in different microemulsions were studied using UV-Visible spectroscopy and phase diagrams of CTAB with modified counter ions CTA+[ZnCl2.Br]- named as CZN-1, CTA+[CuCl2.Br]- named as CCU-1 and CTA+[FeCl3.Br]- named as CFE-1 based upon surfactant with modified counter ions (SMCs). Four different points in microemulsion region of phase diagram were selected with different percentage composition of Smix (surfactant and co-surfactant), oil and RB (taken as water component). The interaction of RB, CCU-1, CFE-1 and CZN-1 within microemulsion environment were studied using Fluorescence spectroscopy. Emission spectra of RB in CCU-1 and CFE-1 based microemulsion confirmed that RB formed complexes with Cu and Fe ions. It was also found that RB was less soluble in CTAB based microemulsion as compared to microemulsions based on SMCs. This novel research study will expose new path for future research work related to microemulsion.

Impact of coriander (Coriandrum sativum), garlic (Allium sativum), fenugreek (Trigonella foenum-graecum) on zootechnical performance, carcass quality, blood metabolites and nutrient digestibility in broilers chickens.

The study investigated the impact of incorporating a specific herbal blend comprising coriander, garlic, and fenugreek (CGF) at various levels on the zootechnical performance, blood metabolites and nutrient digestibility in broiler chickens. The 42-day experiment involved 360 broilers (Cobb 500), organized into four distinct treatment groups. The dietary interventions included a control group consisting of a basal diet and the same diet was supplemented with CGF at rates of 1, 2, and 3%. Broilers receiving a 1% phytogenic mixture exhibited significantly increased live weight and carcass weight. Moreover, the digestibility of crude protein and crude fat significantly improved in broilers supplemented with a 1% phytogenic mixture. On the other hand, the digestibility of calcium and phosphorus showed a notable increase in broilers fed with a 3% phytogenic mixture. Regarding serum metabolites, the 1% phytogenic mixture group displayed significantly higher levels of high density lipoprotein and triglycerides. The supplementation of the broiler diet with a herbal mixture of coriander, fenugreek, and garlic at a 1% rate resulted in improved growth performance, carcass quality, nutrient digestion, and lipid profile.

Nanocarrier-Mediated Drug Delivery via Inhalational Route for Lung Cancer Therapy: A Systematic and Updated Review.

Lung cancer is one of the most severe lethal malignancies, with approximately 1.6 million deaths every year. Lung cancer can be broadly categorised into small and non-small-cell lung cancer. The traditional chemotherapy is nonspecific, destroys healthy cells and produces systemic toxicity; targeted inhalation drug delivery in conjunction with nanoformulations has piqued interest as an approach for improving chemotherapeutic drug activity in the treatment of lung cancer. Our aim is to discuss the impact of polymer and lipid-based nanocarriers (polymeric nanoparticles, liposomes, niosomes, nanostructured lipid carriers, etc.) to treat lung cancer via the inhalational route of drug administration. This review also highlights the clinical studies, patent reports and latest investigations related to lung cancer treatment through the pulmonary route. In accordance with the PRISMA guideline, a systematic literature search was carried out for published works between 2005 and 2023. The keywords used were lung cancer, pulmonary delivery, inhalational drug delivery, liposomes in lung cancer, nanotechnology in lung cancer, etc. Several articles were searched, screened, reviewed and included. The analysis demonstrated the potential of polymer and lipid-based nanocarriers to improve the entrapment of drugs, sustained release, enhanced permeability, targeted drug delivery and retention impact in lung tissues. Patents and clinical observations further strengthen the translational potential of these carrier systems for human use in lung cancer. This systematic review demonstrated the potential of pulmonary (inhalational) drug delivery approaches based on nanocarriers for lung cancer therapy.

Nanocarrier Mediated Intranasal Drug Delivery Systems for the Management of Parkinsonism: A Review.

The transport of drugs to the brain becomes a key concern when treating disorders of the central nervous system. Parkinsonism is one of the major concerns across the world populations, which causes difficulty in coordination and balance. However, the blood-brain barrier is a significant barrier to achieving optimal brain concentration through oral, transdermal, and intravenous routes of administration. The intranasal route with nanocarrier-based formulations has shown potential for managing Parkinsonism disorder (PD). Direct delivery to the brain through the intranasal route is possible via the olfactory and trigeminal pathways using drug-loaded nanotechnology-based drug delivery systems. The critical analysis of reported works demonstrates dose reduction, brain targeting, safety, effectiveness, and stability for drug-loaded nanocarriers. The important aspects of intranasal drug delivery, PD details, and nanocarrier-based intranasal formulations in PD management with a discussion of physicochemical characteristics, cell line studies, and animal studies are the major topics in this review. Patent reports and clinical investigations are summarized in the last sections.

Transfersome, an ultra-deformable lipid-based drug nanocarrier: an updated review with therapeutic applications.

The application of nanotechnology with integration of chemical sciences is increasing continuously in the management of diseases. The drug's physicochemical and pharmacological characteristics are enhanced by application of nanotechnological principles. Several nanotechnology-based formulations are being investigated to improve patient compliance. One such novel nanocarrier system is transfersome (TFS) and is composed of natural biocompatible phospholipids and edge activators. Morphologically, TFS are similar to liposomes but functionally, these are ultra-deformable vesicles which can travel through pores smaller than their size. Because of their amphipathic nature, TFS have the potential to deliver the drugs through sensitive biological membranes, especially the blood-brain barrier, skin layers, and nasal epithelium. Different molecular weight drugs can be transferred inside the cell by encapsulation into the TFS. Knowing the tremendous potentiality of TFS, the present work provides an in-depth and detailed account (pharmaceutical and preclinical characteristics) of TFS incorporating different categories of therapeutic moieties (anti-diabetic, anti-inflammatory, anti-cancer, anti-viral, anti-fungal, anti-oxidant, cardiovascular drugs, CNS acting drugs, vaccine delivery, and miscellaneous applications). It also includes information about the methods of preparation employed, significance of excipients used in the preparation, summary of clinical investigations performed, patent details, latest investigations, routes of administration, challenges, and future progresses related to TFS.

Ameliorative Effect of Pomegranate Peel Powder on the Growth Indices, Oocysts Shedding, and Intestinal Health of Broilers under an Experimentally Induced Coccidiosis Condition.

Coccidiosis stands as one of the most prevalent enteric parasitic diseases in broilers. While antibiotics have traditionally been used for the control of coccidiosis, concerns related to drug residues and the emergence of resistance in chickens have prompted consumer apprehensions. In this study, 600 Ross 308 broiler chicks were randomly divided into five groups: a control group without specific treatments (NC), broilers deliberately exposed to Eimeria tenella (positive control), broilers challenged with E. tenella but dosed with antibiotics (AT), and two groups experimentally exposed to E. tenella while simultaneously receiving pomegranate peel powder (PPE) at dosages of 3 g/kg (3PPP) and 6 g/kg (6PPP). The results revealed that all Eimeria-treated birds exhibited significantly worse growth performance compared to the NC. Notably, a marked improvement was observed in birds infected with E. tenella when supplemented with 6PPP. Both 3PPP and 6PPP supplementation significantly reduced lesion scores, mortality, and oocysts per gram (OPG). Furthermore, histological examination of the cecum indicated that the villus dimensions were restored by PPP supplementation in infected birds. In conclusion, Eimeria-infected birds supplemented with 6PPP experienced an enhanced growth rate, lowered lesion scores, alleviated oocyst shedding, and improved intestinal histological dimensions.

Effect of Lemon (Citrus limon, L.) Peel Powder on Oocyst Shedding, Intestinal Health, and Performance of Broilers Exposed to E. tenella Challenge.

To date, no study has reported the anticoccidial effect of lemon peel powder in broilers. Coccidiosis, caused by Eimeria species, is the prevalent enteric parasitic disease in poultry. Although certain chemical drugs have been used for their control, concerns regarding drug residues and the development of resistance in chickens have arisen among consumers. In this study, a total of 300 Ross 308 broiler chicks were randomly allocated into five groups (five equal replicates of 12 animals). The first group served as the control and did not receive any specific treatment (NC). The second group, referred to as the positive control (PC) group, was deliberately exposed to Eimeria tenella. The third group was challenged with E. tenella and also received treatment with amprolium (1 g/kg) and was designated as AT. The fourth and fifth groups were challenged with E. tenella and simultaneously supplemented with lemon peel powder at a dosage of 3 g/kg (LPP3) and 6 g/kg (LPP6). Sporulated E. tenella oocysts (5 × 104/mL bird) on day 22 of the experiment were administered to the infected broiler chickens. The results indicated that in comparison with the NC, all Eimeria-treated birds exhibited significantly (p < 0.05) lower growth performance. However, a notable improvement was observed when infected birds also received a supplement of LPP3 and LPP6 in their feed. Both LPP3 and LPP6 supplementation significantly (p < 0.05) reduced mortality, lesion scores, and oocyst per gram (OPG) of feces compared with the PC group. Additionally, the histological features of the cecum revealed that villus height, villus width, and crypt depth were partially restored under supplementation with LPP3 and LPP6 in the infected birds. Overall, the results demonstrate that Eimeria-infected birds supplemented with LPP3 and LPP6 exhibited improved growth performance, reduced OPG, lowered intestinal coccidiosis lesion scores, and enhanced intestinal histological features.

Darcy flow of convective and radiative Maxwell nanofluid over a porous disk with the influence of activation energy.

This study reveals an incompressible steady Darcy flow of Maxwell nanofluid by a porous disk with the impact of activation energy. The liquid flow is due to a stretchable rotating disk. The heat equation also includes the impact of heat source/sink and radiation for the purpose of heat transportation. The von Karman transformations are utilized to gain the dimensionless form of ordinary differential equations (ODEs). The solutions are visualised in the form of graphical results using bvp 4c method in Matlab software. The ranges of the associated physical parameters as, 0.0≤ß≤0.9, 0.0≤M≤0.9, 0.0≤λ≤1.5, 0.1≤R≤0.9, -0.2≤s≤1.3, 0.3≤Bi≤0.6, 0.0≤γ≤0.15, 0.1≤Nt≤2.0, 0.2≤Nb≤0.8, 0.0≤Rd≤0.3, 0.0≤σ≤1.5, and 0.0≤E≤0.9 are provided for the graphical solutions developed for the problem. The data of Nussetl and Sherwood numbers are presented here with regard to various physical parameters. According to the numerical results, increasing the Deborah number has a trend to decrease the radial curves. Moreover, the temperature distribution is increased considerably for rising the radiation parameter and the higher rate of the rotation parameter shows a weaker concentration trend. To validate the numerical approach, an excellent comparison is established using a tabular description. To sum up, the current study effectively fills a gap in the antecedent literature.

The Chemical Composition of Soyhulls and Their Effect on Amino Acid and Nutrient Digestibility in Laying Hens during the Peak of Production.

This study investigates the chemical composition of soyhulls (SHs) as an alternative feed ingredient and their effect on nutrient and amino acid (AA) digestibility in laying hens during peak production. A total of 200 golden brown hens (28 weeks old) were subjected to random allocation across 5 dietary treatments: a corn-soybean meal (SBM) reference diet and 4 test diets with 25% SHs from different mills (SH1, SH2, SH3, and SH4). Each treatment was replicated four times with ten birds per replicate. Digesta samples were collected during three phases (28-32, 32-36, and 36-40 weeks of age) to measure apparent metabolizable energy (AME), the apparent ileal digestibility (AID) of nutrients, and the standard ileal digestibility (SID) of AAs. The SBM diet had 30.0% crude protein (CP) and 3.78% crude fiber (CF), while the SH diets had 21.0 to 21.5% CP and 11.6% CF. The findings revealed that the AME was lower (p < 0.05) with SH diets (2404 kcal/kg) compared to the SBM diet (2627 kcal/kg) in all three phases. The SH diets had a lower AID of dry matter (DM), crude protein (CP), ash, ether extract (EE), and crude fiber (CF) than the SBM diet by an average of 2.88, 2.25, 4.93, 4.99, and 3.36%, respectively. The AID of nitrogen-free extract (NFE) was higher in the SH diets than the SBM diet by 3.42% in all three phases (p < 0.05). The SH diets had lower uric acid excretion (about 66.93 mg/100 mL) than the SBM diet (about 76.43 mg/100 mL) on average in all three phases. The SH diets had a lower SID of arginine, histidine, isoleucine, lysine, cysteine, valine, and tyrosine than the SBM diet by 2 to 10%, while the SID of methionine was higher in the SH diets than the SBM diet by 2.2% on average in all three phases (p < 0.05). The SH from Sadiq Brother Feed (SH1) had the highest AME and AID of DM, ash, CP, EE, CF, and the SID of AA among the SH diets. These results indicate that SH can partially replace SBM in laying hen diets, but the source and quality of SH should be considered.

Impact of grape (Vitis vinifera) seed extract on egg production traits, nutrients digestability, lipid peroxidation and fertility of golden laying hens (Gallus gallus) during early stage of production.

Grape by-products represent outstanding alternatives to replace conventional and unsustainable feed sources, given the substantial quantities generated annually by the winery industry. Regrettably, the majority of these by-products are wasted, resulting in significant environmental and economic repercussions. This study was conducted to assess the growth performance, feed efficiency, egg production and quality, lipid peroxidation, fertility and hatchability of reproductive laying hens during their early production stage. A total of 720 golden laying hens, all approximately 25 weeks old and with similar body weights, were randomly assigned to four experimental treatments (six replicates) as follows: control group receiving only the standard diet, (2) a group receiving the standard diet supplemented with grape seed extract at a rate of 250 g/kg (GSE1), (3) a group receiving the standarddiet supplemented with grape seed extract at a rate of 500 g/kg (GSE2), and (4) a group receiving the standarddiet supplemented with grape seed extract at a rate of 750 g/kg (GSE3). There were no significant change (p > 0.05) in feed intak, body weight gain and feed conversion ratio between the control and the experimental groups. Egg weight, egg shell thickness and egg shell weight were significantly (p < 0.05) higher in GSE250 GSE500 and GSE750 compared to the control. The results showed that hen day egg production was also significantly higher (p < 0.05) in GSE500 and GSE 750 compared to the control. Fertility level of GSE 500 and GSE750 was significantly (p < 0.5) higher compared to the control. The MDA level decreased significantly (p < 0.05) in the GSE supplemented birds compared to the control. From these findings, we concluded that GSE 750 had positive impact on egg production, reducing lipid peroxidation and improving fertility in golden laying hens.

Unlocking Insights in IoT-Based Patient Monitoring: Methods for Encompassing Large-Data Challenges.

The remote monitoring of patients using the internet of things (IoT) is essential for ensuring continuous observation, improving healthcare, and decreasing the associated costs (i.e., reducing hospital admissions and emergency visits). There has been much emphasis on developing methods and approaches for remote patient monitoring using IoT. Most existing frameworks cover parts or sub-parts of the overall system but fail to provide a detailed and well-integrated model that covers different layers. The leverage of remote monitoring tools and their coupling with health services requires an architecture that handles data flow and enables significant interventions. This paper proposes a cloud-based patient monitoring model that enables IoT-generated data collection, storage, processing, and visualization. The system has three main parts: sensing (IoT-enabled data collection), network (processing functions and storage), and application (interface for health workers and caretakers). In order to handle the large IoT data, the sensing module employs filtering and variable sampling. This pre-processing helps reduce the data received from IoT devices and enables the observation of four times more patients compared to not using edge processing. We also discuss the flow of data and processing, thus enabling the deployment of data visualization services and intelligent applications.

Identification and Characterization of Phytocyanin Family Genes in Cotton Genomes.

Phytocyanins (PCs) are a class of plant-specific blue copper proteins that have been demonstrated to play a role in electron transport and plant development. Through analysis of the copper ligand residues, spectroscopic properties, and domain architecture of the protein, PCs have been grouped into four subfamilies: uclacyanins (UCs), stellacyanins (SCs), plantacyanins (PLCs), and early nodulin-like proteins (ENODLs). The present study aimed to identify and characterise the PCs present in three distinct cotton species (Gossypium hirsutum, Gossyium arboreum, and Gossypium raimondii) through the identification of 98, 63, and 69 genes respectively. We grouped PCs into four clades by using bioinformatics analysis and sequence alignment, which exhibit variations in gene structure and motif distribution. PCs are distributed across all chromosomes in each of the three species, with varying numbers of exons per gene and multiple conserved motifs, and with a minimum of 1 and maximum of 11 exons found on one gene. Transcriptomic data and qRT-PCR analysis revealed that two highly differentiated PC genes were expressed at the fibre initiation stage, while three highly differentiated PCs were expressed at the fibre elongation stage. These findings serve as a foundation for further investigations aimed at understanding the contribution of this gene family in cotton fibre production.

Emerging Promise of Therapeutic Approaches Targeting Mitochondria in Neurodegenerative Disorders.

Mitochondria are critical for homeostasis and metabolism in all cellular eukaryotes. Brain mitochondria are the primary source of fuel that supports many brain functions, including intracellular energy supply, cellular calcium regulation, regulation of limited cellular oxidative capacity, and control of cell death. Much evidence suggests that mitochondria play a central role in neurodegenerative disorders (NDDs) such as Parkinson's disease, Alzheimer's disease, Huntington's disease, and amyotrophic lateral sclerosis. Ongoing studies of NDDs have revealed that mitochondrial pathology is mainly found in inherited or irregular NDDs and is thought to be associated with the pathophysiological cycle of these disorders. Typical mitochondrial disturbances in NDDs include increased free radical production, decreased ATP synthesis, alterations in mitochondrial permeability, and mitochondrial DNA damage. The main objective of this review is to highlight the basic mitochondrial problems that occur in NDDs and discuss the use mitochondrial drugs, especially mitochondrial antioxidants, mitochondrial permeability transition blockade, and mitochondrial gene therapy, for the treatment and control of NDDs.

Nanocarrier Based Delivery of Berberine: A Critical Review on Pharmaceutical and Preclinical Characteristics of the Bioactive.

Berberine (BBR) is an isoquinoline alkaloid with several therapeutic properties, including anti-microbial, anti-diarrhea, anti-viral, anti-inflammatory, antihypertensive, anti-tumor, and anti-diabetes. However, its low water solubility, low absorption, first-pass metabolism, nontargeting, and poor bioavailability represent major hurdles to its successful therapeutic applications. Hence, researchers have attempted to enhance the biological and pharmacological activity of BBR to overcome its drawbacks by encapsulation of BBR in micro and nano delivery systems. For the preparation of nanostructured carrier systems of BBR, a range of methods has been developed, and each method has its benefits and characteristics. This review critically describes different types of nanocarriers like liposomes, niosomes, ethosomes, nanoemulsions, polymeric nanoparticles, micelles, dendrimers, and silver and gold nanoparticles that have been used for encapsulation of BBR for different therapeutic applications. The various pharmaceutical characteristics (size, shape, entrapment efficiency, zeta potential, drug release, and drug permeation) of these BBR-loaded nanocarriers have been discussed systematically. Preclinical studies of BBR nanoformulations involving animal models are also discussed.

Formulation and Development of Curcumin-Piperine-Loaded S-SNEDDS for the Treatment of Alzheimer's Disease.

Curcumin (CUR) and piperine (PIP) are very well-known phytochemicals that claimed to have many health benefits and have been widely used in foods and traditional medicines. This study investigated the therapeutic efficacy of these compounds to treat Alzheimer's disease (AD). However, poor oral bioavailability and permeability of curcumin are a major challenge for formulation scientists. In this research study, the researcher tried to enhance the bioavailability and permeability of curcumin by a nanotechnological approach. In this research study, we developed a CUR-PIP-loaded SNEDDS in various oils. Optimised formulation NF3 was subjected to evaluate its therapeutic effectiveness on AD animal model in comparison with untreated AD model and treated group (by market formulation donepezil). On the basis of characterisation results, it is confirmed that NF3 formulation is the best formulation. The optimised formulation shows a significant dose-dependent manner therapeutic effect on AD-induced model. Novel formulation CUR-PIP solid-SNEDDS was successfully developed and optimised. It is expected that the developed S-SNEDDS can be a potential, safe and effective carrier for the oral delivery of curcumin to the brain. To date, this article is the only study of CUR-PIP-loaded S-SNEDDS for the treatment of AD.

Development and Evaluation of Topical Ethosomal Gel for Fungal Infections.

BACKGROUND: Fungal infections are one of the most common dermatological issues worldwide. Candida species-caused fungal infections are frequent on the cutaneous surface. Eberconazole (EBZ) has the strongest antifungal action against Candida spp., the major source of fungal infections. METHOD: In the present study, the cold method followed by probe sonication was used to create EBZ-loaded ethosomal dispersion. The solubility of ethosomes in different lipids and surfactants was used to choose these components. Under magnetic stirring, the dispersion was absorbed into a carbopol 934 gel. In vitro antifungal activity was performed using the Agar well diffusion method, and their topical effectiveness against pathogenic Candida albicans was compared to that of a marketed formulation containing EBZ. RESULTS: Eberconazol incorporated into gel displayed sustained release in an in vitro release assay. Based on the zone of inhibition diameters, EBZ formulation was determined to be efficient against C. albicans when compared to the commercialized cream and plain gel. CONCLUSION: Based on these findings, the current study found that EBZ possesses significant antifungal efficacy against C. albicans.

Exploring the management approaches of cytokines including viral infection and neuroinflammation for neurological disorders.

Considerable evidence supports that cytokines are important mediators of pathophysiologic processes within the central nervous system (CNS). Numerous studies have documented the increased production of various cytokines in the human CNS in various neurological and neuropsychiatric disorders. Deciphering cytokine actions in the intact CNS has important implications for our understanding of the pathogenesis and treatment of these disorders. The purpose of this study is to discuss the recent research on treating cytokine storm and amyloids, including stroke, Parkinson's disease (PD), Alzheimer's disease (AD), Huntington's condition, Multi-sclerosis (MS), Amyotrophic Lateral Sclerosis (ALS). Neuroinflammation observed in neurological disorders has a pivotal role in exacerbating Aß burden and tau hyperphosphorylation, suggesting that stimulating cytokines in response to an undesirable external response could be a checkpoint for treating neurological disorders. Furthermore, the pro-inflammatory cytokines help our immune system through a neuroprotective mechanism in clearing viral infection by recruiting mononuclear cells. This study reveals that cytokine applications may play a vital role in providing novel regulation and methods for the therapeutic approach to neurological disorders and the causes of the deregulation, which is responsible for neuroinflammation and viral infection. However, it needs to be further investigated to clarify better the mechanisms of cytokine release in response to various stimuli, which could be the central point for treating neurological disorders.

Correlation of histopathological patterns of OSCC patients with tumor site and habits.

INTRODUCTION: Oral cancer is considered a major global public health problem. The causes of OSCC are tobacco, alcohol, viral infections such as EBV, HPV, and herpes simplex virus, poor oral hygiene (including sharp teeth and decay), ill-fitting denture, ultraviolet (UV) exposure, nutrition, and genetic predisposition. The etiology of oral cancer varies in different populations due to area-specific etiological factors. OBJECTIVE: Finding a correlation of histopathological pattern to the tumor site and habits as an outcome of OSCC. METHODS: This cross-sectional study was conducted in Karachi, Pakistan. A total of 100 known cases of an oral squamous cell carcinoma were diagnosed with the help of biopsy reports and were examined for histopathologic features, site of the lesion, and risk habits. RESULTS: 48 years was the mean age at the time of diagnosis with a distribution of 61% men and 39% women. The frequently affected site was buccal mucosa and the prime risk habit was gutka followed by betel quid. Histologically, the degree of differentiation shows that moderately differentiated OSCC was most commonly present, while the most prevalent histopathological pattern was spindle cell carcinoma. The statistical relation between lesion site and tobacco habits was found to be significant with a p value (p = 0.01). CONCLUSION: Rates of oral squamous cell carcinoma are higher in males than females with a mean age at the time of diagnosis being less than 50 years. Frequently placing gutka in the buccal vestibule against buccal mucosa is responsible to make buccal mucosa the most common tumor site. This study provides baseline information regarding habits.

Clinical outcomes of multidimensional association of type 2 diabetes mellitus, COVID-19 and sarcopenia: an algorithm and scoping systematic evaluation.

BACKGROUND: The aim of this study was to provide a scoping and comprehensive review for the clinical outcomes from the cross-link of Type 2 diabetes mellitus (T2DM), COVID-19, and sarcopenia. METHODS: By using PRISMA guidelines and searching through different databases that could provide findings of evidence on the association of T2DM, COVID-19, and sarcopenia. RESULTS: Thirty-three studies reported a relationship between sarcopenia with T2DM, twenty-one studies reported the prognosis COVID-19 in patients with T2DM, ten studies reported the prognosis of COVID-19 in patients with sarcopenia, five studies discussed the outcomes of sarcopenia in patients with COVID-19, and one study reported sarcopenia outcomes in the presence of T2DM and COVID-19. CONCLUSION: There is an obvious multidimensional relationship between T2DM, COVID-19 and sarcopenia which can cause prejudicial effects, poor prognosis, prolonged hospitalisation, lowered quality of life and a higher mortality rate during the current COVID-19 pandemic.
