An expert consensus statement on biomarkers of ageing for use in intervention studies.

Biomarkers of ageing serve as important outcome measures in longevity-promoting interventions. However, there is limited consensus on which specific biomarkers are most appropriate for human intervention studies. This work aimed to address this need by establishing an expert consensus on biomarkers of ageing for use in intervention studies via the Delphi method.

Seropositivity and coinfection of hepatitis B and hepatitis C viruses in Central India: A hospital-based study.

Background: Hepatitis B virus (HBV) and Hepatitis C virus (HCV) show similarity in the transmission, distribution, hepatotropism, and leading to chronic asymptomatic infection. Coinfection of HBV and HCV can lead to more severe liver disease and an increased risk for progression to hepatocellular carcinoma (HCC). Most of the people with chronic infection are unaware of their HBV and HCV infections, hence facilitating these to go undiagnosed until these viruses have caused serious liver damage and they act as a potential source of infection for the community at large.

Increasing adult-born neurons protects mice from epilepsy.

Neurogenesis occurs in the adult brain in the hippocampal dentate gyrus, an area that contains neurons which are vulnerable to insults and injury, such as severe seizures. Previous studies showed that increasing adult neurogenesis reduced neuronal damage after these seizures. Because the damage typically is followed by chronic life-long seizures (epilepsy), we asked if increasing adult-born neurons would prevent epilepsy.

-Difluoroallene (DFA): an emerging versatile synthetic precursor to enable diverse fluorinated molecules.

Organofluorine compounds are increasingly found in diverse fields, such as pharmaceuticals, agrochemicals, and materials science. -Difluoroallenes, which have -difluoro alkenes and allenes-like properties, offer a distinct and adaptable platform for novel synthetic transformations. Their distinctiveness is highlighted by various strategies, where the -difluoro group's presence plays a pivotal role in successful reactions.

In Silico Investigation of Suillin Derived from Suillus luteus Mushroom (Agaricomycetes) Targeting Acetylcholinesterase: Docking and Virtual Screening Study.

This study integrates bioinformatics and computer-aided drug discovery to assess suillin's therapeutic potential, particularly its interaction with acetylcholinesterase (AChE). Alzheimer's disease presents profound challenges, necessitating effective treatments to mitigate cognitive decline and improve patients' quality of life. Although current medications offer symptomatic relief, they often entail adverse effects and do not address the underlying disease progression.

Pleomorphic xanthoastrocytoma with NTRK fusion presenting as spontaneous intracranial hemorrhage-case report and literature review.

Background: Pleomorphic xanthoastrocytoma (PXA) is a rare brain tumor that accounts for <1% of all gliomas. An in-depth understanding of PXA's molecular makeup remains a work in progress due to its limited numbers globally. Separately, spontaneous intracranial hemorrhage (pICH) is an uncommon but potentially devastating emergency in young children, often caused by vascular malformations or underlying hematological conditions.

Choline supplementation in early life improves and low levels of choline can impair outcomes in a mouse model of Alzheimer's disease.

Maternal choline supplementation (MCS) improves cognition in Alzheimer's disease (AD) models. However, the effects of MCS on neuronal hyperexcitability in AD are unknown. We investigated the effects of MCS in a well-established mouse model of AD with hyperexcitability, the Tg2576 mouse.

Pd-Catalyzed Cascade Heck/C(sp)-H Activation for Spirocyclopropyl Oxindoles.

We have demonstrated a Pd(0)-catalyzed Heck/C(sp)-H activation cascade for the synthesis of spirocyclopropyl oxindoles in high yields from easily accessible -bromoacrylamides. The formation of spirocyclopropyl oxindole is guided by an unconventional four-membered palladacycle through C(sp)-H activation. The reaction exhibits a wide range of substrate scope and operates efficiently with a mere 0.

Successful Extension of Vascularized Composite Allograft Perfusion Cold Storage to 24 h in a Rat Hindlimb Transplant Model.

Background: Vascularized composite allograft transplantation is a treatment option for complex tissue injuries; however, ischemia reperfusion injury and high acute rejection rates remain a challenge. Hypothermic machine perfusion using acellular storage perfusate is a potential solution. This study evaluated the University of Wisconsin Kidney Preservation Solution-1 (KPS-1) compared with normal saline (NS) for preservation of donor rat hindlimbs subjected to 24 h of ex vivo perfusion cold storage.

A remarkable genetic shift in a transmitted/founder virus broadens antibody responses against HIV-1.

A productive HIV-1 infection in humans is often established by transmission and propagation of a single transmitted/founder (T/F) virus, which then evolves into a complex mixture of variants during the lifetime of infection. An effective HIV-1 vaccine should elicit broad immune responses in order to block the entry of diverse T/F viruses. Currently, no such vaccine exists.

Customised pre-operative cranioplasty to achieve maximal surgical resection of tumours with osseous involvement-a case series.

Purpose: Surgical resection with bony margins would be the treatment of choice for tumours with osseous involvement such as meningiomas and metastasis. By developing and designing pre-operative customised 3D modelled implants, the patient can undergo resection of meningioma and repair of bone defect in the same operation. We present a generalisable method for designing pre-operative cranioplasty in patients to repair the bone defect after the resection of tumours.

Impact of Hyperuricemia and Urate-Lowering Agents on Cardiovascular Diseases.

The association between hyperuricemia and cardiovascular diseases has been studied for many years. Research has shown a link between high uric acid levels and increased risk of including coronary artery disease hypertension and other cardiovascular conditions. Urate-lowering therapy, particularly with xanthine oxidase inhibitors like allopurinol, has shown promising results in reducing blood pressure in individuals with hyperuricemia and hypertension.

Diuretic resistance and the role of albumin in congestive heart failure.

Diuresis with loop diuretics is the mainstay treatment for volume optimization in patients with congestive heart failure, in which perfusion and volume expansion play a crucial role. There are robust guidelines with extensive evidence for the management of heart failure; however, clear guidance is needed for patients who do not respond to standard diuretic treatment. Diuretic resistance (DR) can be defined as an insufficient quantity of natriuresis with proper diuretic therapy.

A comprehensive analysis towards exploring the promises of AI-related approaches in autism research.

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that presents challenges in communication, social interaction, repetitive behaviour, and limited interests. Detecting ASD at an early stage is crucial for timely interventions and an improved quality of life. In recent times, Artificial Intelligence (AI) has been increasingly used in ASD research.

COVID-19-Induced Cardiac Tamponade: A Case Study and a Literature Review.

COVID-19 presentation is heterogeneous. As a viral illness, it could cause pericardial effusion leading to cardiac tamponade. We present a patient coursing with this viral illness that was found to have cardiac tamponade.

Increasing adult-born neurons protects mice from epilepsy.

Neurogenesis occurs in the adult brain in the hippocampal dentate gyrus, an area that contains neurons which are vulnerable to insults and injury, such as severe seizures. Previous studies showed that increasing adult neurogenesis reduced neuronal damage after these seizures. Because the damage typically is followed by chronic life-long seizures (epilepsy), we asked if increasing adult-born neurons would prevent epilepsy.

Diagnostic dilemma in acute neurological presentation of spinal arachnoid cysts: A case report.

Background: Spinal arachnoid cysts are relatively uncommon, cerebrospinal fluid-filled sacs formed by arachnoid membranes that can be either idiopathic or acquired. The neurological presentation of these cysts is varied. Advances in imaging techniques have allowed an improved characterization of these entities and excluded other possible causes of clinical manifestation.

Cu(I)/-Imine Ligand Catalyzed C(sp)-C(sp) Coupling of Alkyl Bromides with Alkynes: Scope and Mechanistic Investigation.

We have developed an efficient Cu/,-bidentate imine ligand catalytic system for C(sp)-C(sp) coupling to obtain internal alkynes, di/trisubstituted allenes and strained bridged cyclic lactams in moderate to excellent yields from readily available alkyl(benzyl) bromides in one-pot transformation. Density Functional Theory (DFT) assisted mechanistic study along with control experiments support the involvement of bialkynylated copper species which undergo single electron transfer (SET) with alkyl halides to generate radical intermediate in the reaction. The ,-bidentate imine ligand plays a vital role in stabilization of intermediate copper complex and facilitates the product formation.

Fracture resistance of post and core in immediate and delayed post space in trauma simulated teeth.

Introduction: This research aims to assess and analyze the fracture resistance of GC Everstick post with separate composite core buildup and Edelweiss prefabricated resin composite post and core single unit into immediate and delayed post space prepared teeth.

Methods: A total of 120 extracted human mandibular premolars have been subjected to a standardized protocol of mechanical trauma to simulate tooth fracture. Teeth samples were randomly divided into four groups (n = 30) on the basis of time taken for the preparation of post space (approximately following root canal obturation and 24 h after root canal obturation) for the single unit Edelweiss post and core system and GC post with separate core buildup.

Inherited thrombophilia: undetected comorbidity complicating COVID-19 infection.

The relation between the severity of COVID-19 and coexisting undiagnosed underlying thrombophilic conditions is not yet established. It may be possible that undiagnosed thrombophilia exaggerates an already pro-thrombotic state in COVID-19 patients and may be responsible for severe disease in absence of any known co-morbidity. The aim was to analyze the association of underlying thrombophilia with the severity of COVID-19 infection in post-COVID patients after a minimum of 6 weeks of recovery and to compare thrombophilia profile in severe versus non-severe COVID-19 patients.
