    Abstract The Central nervous system (CNS) is the prime regulator of signaling pathways whose function includes regulation of food intake (consumption), energy expenditure, and other metabolic responses like glycolysis, gluconeogenesis, fatty acid oxidation, and thermogenesis that have been implicated in chronic inflammatory disorders. Type 2 diabetes mellitus (T2DM) and obesity are two metabolic disorders that are linked together and have become an epidemic worldwide, thus raising significant public health concerns. Fibroblast growth factor 21 (FGF21) is an endocrine hormone with pleiotropic metabolic effects that increase insulin sensitivity and energy expenditure by elevating thermogenesis in brown or beige adipocytes, thus reducing body weight and sugar intake. In contrast, during starvation conditions, FGF21 induces its expression in the liver to initiate glucose homeostasis. Insulin resistance is one of the main anomalies caused by impaired FGF21 signaling, which also causes abnormal regulation of other signaling pathways. Tumor necrosis factor alpha (TNF-α), the cytokine released by adipocytes and inflammatory cells in response to chronic inflammation, is regarded major factor that reduces the expression of FGF21 and modulates underlying insulin resistance that causes imbalanced glucose homeostasis. This review aims to shed light on the mechanisms underlying the development of insulin resistance in obese individuals as well as the fundamental flaw in type 2 diabetes, which is malfunctioning obese adipose tissue.

    Abstract Photocatalysis has proven to be an effective approach for the production of reactive intermediates under moderate reaction conditions. The possibility for the green synthesis of high-value compounds using the synergy of photocatalysis and biocatalysis, benefiting from the selectivity of enzymes and the reactivity of photocatalysts, has drawn growing interest. Mechanistic investigations, substrate analyses, and photobiocatalytic chemical transformations will all be incorporated in this review. We seek to shed light on upcoming synthetic opportunities in the field by precisely describing mechanistically unique techniques in photobiocatalytic chemistry.

    Abstract Alzheimer's disease (AD), is the major type of dementia and most progressive, irreversible widespread neurodegenerative disorder affecting the elderly worldwide. The prime hallmarks of Alzheimer's disease (AD) are beta-amyloid plaques (Aβ) and neurofibrillary tangles (NFT). In spite of recent advances and developments in targeting the hallmarks of AD, symptomatic medications that promise neuroprotective activity against AD are currently unable to treat degenerating brain clinically or therapeutically and show little efficacy. The extensive progress of AD therapies over time has resulted in the advent of disease-modifying medications with the potential to alleviate AD. However, due to the presence of a defensive connection between the vascular system and the neural tissues known as the blood-brain barrier (BBB), directing these medications to the site of action in the degenerating brain is the key problem. BBB acts as a highly selective semipermeable membrane that prevents any type of foreign substance from entering the microenvironment of neurons. To overcome this limitation, the revolutionary approach of nanoparticle(NP)/nanocarrier-mediated drug delivery system has marked the era with its unique property to cross, avoid, or disrupt the defensive BBB efficiently and release the modified drug at the target site of action. After comprehensive data mining, this review focuses on the detailed understanding of different types of nanoparticle(NP)/nanocarrier-mediated drug delivery system like liposomes, micelles, gold nanoparticles(NP), polymeric NPs, etc. which have promising potential in carrying the desired drug(cargo) to the location in the degenerated brain thus mitigating the Alzheimer's disease.

    Abstract Aims: Phase I of the
    Methods: Using a multistage random sampling technique, 1,223 pregnant women locally registered in the rural field practice area of a block were identified. Those requiring HIP screening were subjected to a 2-h 75 g oral glucose tolerance test during the house visit irrespective of their period-of-gestation and last meal timings, diagnosed using the Diabetes in Pregnancy Study Group India (DIPSI) criterion (when indicated). Data were collected by personal interviews using a pretested data collection tool. Statistical Package for Social Sciences version 20.0 was used for analysis.
    Results: The overall HIP prevalence recorded was 9.7% (95% CI: 8.1-11.5%); the majority (95.8%) were GDM followed by overt DIP (4.2%). Less than 1% of the subjects (0.7%) self-reported pre-GDM. Despite this burden, more than three-fourths were never screened for HIP in their pregnancy. Of those tested, the majority availed secondary healthcare facilities. Few even had to bear expenses in private with a very handful being tested free-of-cost by ANM in the community; findings that altogether sharply contrast to those recommended by national protocols.
    Conclusion: Despite the high HIP burden, beneficiaries are unable to utilize community-related universal screening protocols as desired.

    Abstract Background: Both cesarean-section (CS) delivery (CD) and vaginal delivery (VD) is associated with well-known measurable short- and long-term maternal and neonatal complications and benefits. Objective: The present retrospective observational study was conducted on a preliminary basis to evaluate the contributing factors that provoke CS delivery. Materials and Methods: The short-term (6 months) retrospective study was conducted at the Department of Obstetrics and Gynaecology, Pt. Deen Dayal Upadhyay and Northern Railway divisional hospital Moradabad, Uttar Pradesh, India. The sample size was calculated accordingly with a relative precision of 10.2% of prevalence and was found to be 140 and we have taken the sample size of 345. Results: The prevalence of CD for a particular course of duration was found to be 36.23%. The risk of CD increased (P < 0.001) with increased BMI. However, differential limits of normal BMI signify that lower limit of normal BMI possessed high % of CS. As the education profile was getting high the possibility of CS was found to be increased (P < 0.001). Women with negative Rh factor the probability of CS in terms of percentage was found to be 87.5%. There was a proportionate possibility of CS with an increased gap between parities. The % mortality of new-born by CD and VD was 14.28% and 85.71%, respectively, which signifies that CS prevents infant mortality. There was 99.2% possibility of undergoing CS if a woman possessing medical complications. Conclusion: The present study acknowledged that CD ensures feto-maternal safety. However, the study also highlighted some probable indications that might engender CD.
