Simple Anthropometric Indices are Useful for Predicting Non-alcoholic Fatty Liver Disease [NAFLD] in Asian Indians.

Background And Aims: With the rising prevalence of obesity and metabolic syndrome, nonalcoholic fatty liver disease (NAFLD) has become the most common liver disorder in both developed and developing nations. Several studies on NAFLD have described waist circumference, a surrogate marker of visceral fat accumulation and waist height ratio as a better screening tool for NAFLD and metabolic syndrome than body mass index (BMI). We conducted this study to assess simple abdominal obesity indices as a predictor of NAFLD and determine the appropriate cut-off levels with reference to NAFLD.

PUMA dependent mitophagy by Abrus agglutinin contributes to apoptosis through ceramide generation.

PUMA, a BH3-only pro-apoptotic Bcl2 family protein, is known to translocate from the cytosol into the mitochondria in order to induce apoptosis. Interestingly, the induction of PUMA by p53 plays a critical role in DNA damage-induced apoptosis. In this study, we reported mitophagy inducing potential of PUMA triggered by phytolectin Abrus agglutinin (AGG) in U87MG glioblastoma cells and established AGG-induced ceramide acts as the chief mediator of mitophagy dependent cell death through activation of both mitochondrial ROS as well as ER stress.

The review article commences with a precise description of the importance of NI moiety and its several restricted area of applications owing to its aggregation caused quenching (ACQ) properties, followed by the discovery and importance of AIE/AIEE-active NIs. The introduction section tracked an overview of the state of the art in NI luminogens in multiple applications.

Macrophages sensing oxidized DAMPs reprogram their metabolism to support redox homeostasis and inflammation through a TLR2-Syk-ceramide dependent mechanism.

Objective: Macrophages control tissue homeostasis and inflammation by sensing and responding to environmental cues. However, the metabolic adaptation of macrophages to oxidative tissue damage and its translation into inflammatory mechanisms remains enigmatic.

Methods: Here we identify the critical regulatory pathways that are induced by endogenous oxidation-derived DAMPs (oxidized phospholipids, OxPL) in vitro, leading to formation of a unique redox-regulatory metabolic phenotype (Mox), which is strikingly different from conventional classical or alternative macrophage activation.

Nondysraphic cervicomedullary intramedullary lipoma.

Spinal cord lipomas are usually associated with spinal dysraphism and is most common in lumbosacral region. Spinal intradural lipoma is a rare condition accounting for less than 1% of spinal cord tumours and is most prevalent in cervicodorsal region. Intramedullary spinal cord lipoma of cervical spine not associated with spinal dysraphism is one of the rarest lesions.

Enhancing elevated temperature strength of copper containing aluminium alloys by forming L1 AlZr precipitates and nucleating θ″ precipitates on them.

Strengthening by precipitation of second phase is the guiding principle for the development of a host of high strength structural alloys, in particular, aluminium alloys for transportation sector. Higher efficiency and lower emission demands use of alloys at higher operating temperatures (200 °C-250 °C) and stresses, especially in applications for engine parts. Unfortunately, most of the precipitation hardened aluminium alloys that are currently available can withstand maximum temperatures ranging from 150-200 °C.

Elimination of dysfunctional mitochondria through mitophagy suppresses benzo[a]pyrene-induced apoptosis.

Mitophagy, a special type of autophagy, plays an important role in the mitochondria quality control and cellular homeostasis. In this study, we examined the molecular mechanism of mitophagy induction with benzo[a]pyrene (B[a]P), a ubiquitous polycyclic aromatic hydrocarbon, which acts as a prosurvival response against apoptotic cell death. Our study showed that B[a]P displayed higher cytotoxicity in autophagy-deficient HaCaT cells as compared to control.

Duality and quantum state engineering in cavity arrays.

A system of two coupled cavities with N - 1 photons is shown to be dynamically equivalent to an array of N coupled cavities containing one photon. Every transition in the two cavity system has a dual phenomenon in terms of photon transport in the cavity array. This duality is employed to arrive at the required coupling strengths and nonlinearities in the cavity array so that controlled photon transfer is possible between any two cavities.

Massive juvenile nasopharyngeal angiofibroma: ode to the open surgical approach.

The management of juvenile nasopharyngeal angiofibroma has undergone a significant evolution, with more surgeons moving towards the minimal invasive endoscopic approaches. Although considered the standard of care by most, an endoscopic approach may not be sufficient for extensive tumours, as exemplified by the current case of a young man presenting with the largest juvenile nasopharyngeal angiofibroma described in English literature until the present that was eventually excised via an anterior external approach.

Click Biotinylation of PLGA Template for Biotin Receptor Oriented Delivery of Doxorubicin Hydrochloride in 4T1 Cell-Induced Breast Cancer.

PLGA was functionalized with PEG and biotin using click chemistry to generate a biotin receptor targeted copolymer (biotinylated-PEG-PLGA) which in turn was used to fabricate ultrafine nanoparticles (BPNP) of doxorubicin hydrochloride (DOX) for effective delivery in 4T1 cell induced breast cancer. However, adequate entrapment of a hydrophilic bioactive like DOX in a hydrophobic polymer system made of PLGA is not usually possible. We therefore modified a conventional W/O/W emulsion method by utilizing NHCl in the external phase to constrain DOX in dissolved polymer phase by suppressing DOX's inherent aqueous solubility as per common ion effect.

Nucleobase Protection of Deoxyribo- and Ribonucleosides.

Oligonucleotides carrying a variety of chemical modifications including conjugates are finding increasing applications in therapeutics, diagnostics, functional genomics, proteomics, and as research tools in chemical and molecular biology. The successful synthesis of oligonucleotides primarily depends on the use of appropriately protected nucleoside building blocks including the exocyclic amino groups of the nucleobases, the hydroxyl groups at the 2'-, 3'-, and 5'-positions of the sugar moieties, and the internucleotide phospho-linkage. This unit is a thoroughly revised update of the previously published version and describes the recent development of various protecting groups that facilitate reliable oligonucleotide synthesis.

Conformational transition of κ-casein in micellar environment: Insight from the tryptophan fluorescence.

Intrinsically disordered proteins (IDPs) are under intense analysis due to their structural flexibility and importance in biological functions. Minuscule modulation in the microenvironment induces significant conformational changes in IDPs, and these non-native conformations of the IDPs often induce aggregation and cause cell death. Changes in the membrane composition often change the microenvironment, which promote conformational change and aggregation of IDPs.
