Oncostatin M Improves Cutaneous Wound Re-Epithelialization and Is Deficient under Diabetic Conditions.

Impaired re-epithelialization characterized by hyperkeratotic nonmigratory wound epithelium is a hallmark of nonhealing diabetic wounds. In chronic wounds, the copious release of oncostatin M (OSM) from wound macrophages is evident. OSM is a potent keratinocyte (KC) activator.

Macrophage monocarboxylate transporter 1 promotes peripheral nerve regeneration after injury in mice.

Peripheral nerves have the capacity for regeneration, but the rate of regeneration is so slow that many nerve injuries lead to incomplete recovery and permanent disability for patients. Macrophages play a critical role in the peripheral nerve response to injury, contributing to both Wallerian degeneration and nerve regeneration, and their function has recently been shown to be dependent on intracellular metabolism. To date, the impact of their intracellular metabolism on peripheral nerve regeneration has not been studied.

Multiple strategies of plant colonization by beneficial endophytic Enterobacter sp. SA187.

Although many endophytic plant growth-promoting rhizobacteria have been identified, relatively little is still known about the mechanisms by which they enter plants and promote plant growth. The beneficial endophyte Enterobacter sp. SA187 was shown to maintain the productivity of crops in extreme agricultural conditions.

Immunoglobulins and Lymphocyte Subsets in Children with Infantile Tremor Syndrome.

In this hospital-based, cross-sectional study, immunoglobulin levels and lymphocyte subsets status were evaluated in children with infantile tremor syndrome (ITS) [neurocutaneous infantile B12 deficiency (NIB) syndrome]. Blood samples were drawn at the baseline (n = 28) and at 6 wk (n = 25) after treatment. A low IgG/IgA or IgM was more likely in untreated children than post-treatment (p = 0.

An updated review on Mendelian susceptibility to mycobacterial diseases- a silver jubilee celebration of its first genetic diagnosis.

: Mendelian susceptibility to mycobacterial diseases (MSMD), a group of at least 18 different genetic disorders, encompasses a specific class of inborn errors of immunity that result in predilection to infection with mycobacteria including the weakly virulent strains. Primarily, these consist of defects in the IFN-γ-IL-12/23 circuit that is crucial for immunity against intracellular microorganisms. Although the first genetic etiology of MSMD was discovered in 1996, molecular diagnosis of MSMD in resource-constrained settings may remain far-fetched.

Huntingtin fibrils with different toxicity, structure, and seeding potential can be interconverted.

The first exon of the huntingtin protein (HTTex1) important in Huntington's disease (HD) can form cross-β fibrils of varying toxicity. We find that the difference between these fibrils is the degree of entanglement and dynamics of the C-terminal proline-rich domain (PRD) in a mechanism analogous to polyproline film formation. In contrast to fibril strains found for other cross-β fibrils, these HTTex1 fibril types can be interconverted.

Clinical profile, long-term follow-up and outcome of juvenile systemic scleroderma: 25 years of clinical experience from North-West India.

Objectives: To describe the clinical profile, long-term follow-up and outcome of juvenile systemic scleroderma (JSSc) from a tertiary care referral hospital in North-West India.

Methods: A review of case records was performed and children with JSSc (disease onset <14 years of age) were analysed. Diagnosis was based on the Paediatric Rheumatology European Society/American College of Rheumatology/European League against Rheumatism provisional classification criteria for JSSc.

Preparation, characterization and agri applications of biochar produced by pyrolysis of sewage sludge at different temperatures.

Sewage sludge (SS) is an abundantly available feedstock, which is generally considered as potential threat to human health and environment. Its utilization in any process would be of great help for environmental sustainability. Accordingly, this work aimed to prepare and characterize the sewage sludge biochar (SSB) at temperatures, i.

False-positive HIV serology, Candida lusitaniae pneumonia, and a novel mutation in the CYBB gene.

Background: Chronic granulomatous disease (CGD) presents with a myriad of clinical manifestations pertaining to both immunodeficiency and hyperinflammation. Although Candida infection is a signature organism for patients with CGD, C. lusitaniae pneumonia in CGD has rarely been reported.

Hematologically important mutations: X-linked chronic granulomatous disease (fourth update).

Chronic granulomatous disease (CGD) is an immunodeficiency disorder affecting about 1 in 250,000 individuals. CGD patients suffer from severe bacterial and fungal infections. The disease is caused by a lack of superoxide production by the leukocyte enzyme NADPH oxidase.

Droplet and fibril formation of the functional amyloid Orb2.

The functional amyloid Orb2 belongs to the cytoplasmic polyadenylation element binding (CPEB) protein family and plays an important role in long-term memory formation in Drosophila. The Orb2 domain structure combines RNA recognition motifs with low-complexity sequences similar to many RNA-binding proteins shown to form protein droplets via liquid-liquid phase separation (LLPS) in vivo and in vitro. This similarity suggests that Orb2 might also undergo LLPS.

Structure-Tailored Non-Noble Metal-based Ternary Chalcogenide Nanocrystals for Pt-like Electrocatalytic Hydrogen Production.

A facile microwave-assisted strategy was employed to synthesize Ni Bi S nanocrystals. Variation in the synthesis conditions tuned the composition of monoclinic and orthorhombic phases of Ni Bi S . The electrochemical hydrogen evolution activity of the catalyst with highest percentage of monoclinic phase demonstrated a negligible onset potential of only 24 mV close to that of state-of-the-art Pt/C with an overpotential as low as 88 mV.

Congenital Rubella: A Salient Cause of Congenital Heart Defects in Infants.

Background: Structural congenital heart defects (CHD) take a huge toll of congenital defects in children in India. Limited information is available regarding modifiable risk factors for its causation. This study was planned with an aim to determine the prevalence of congenital rubella infection in Indian infants with structural CHD's.

A total of ten patients with MRONJ underwent sequestrectomy and reconstruction using BFP. There were 3 males and 7 females.

Cysteine proteases: Battling pathogenic parasitic protozoans with omnipresent enzymes.

Millions of people worldwide lie at the risk of parasitic protozoic infections that kill over a million people each year. The rising inefficacy of conventional therapeutics to combat these diseases, mainly due to the development of drug resistance to a handful of available licensed options contributes substantially to the rising burden of these ailments. Cysteine proteases are omnipresent enzymes that are critically implicated in the pathogenesis of protozoic infections.

Skewed TCR Alpha, but not Beta, Gene Rearrangements and Lymphoma Associated with a Pathogenic TRAC Variant.

We report a non-consanguineous family from North-west India in which 3 siblings succumbed to a rare variant of combined immunodeficiency. All three had similar clinical and immunological profiles. However, the youngest child also developed Non-Hodgkin lymphoma in infancy.

Theoretical Study of the Energy Disposal Mechanism and the State-Resolved Quantum Dynamics of the H + LiH → H + Li Reaction.

Despite several studies in the literature, the detailed quantum state-to-state level mechanism of the astrophysically important exoergic barrierless H + LiH → H + Li reaction is yet to be understood. In this work, we have investigated the energy disposal mechanism of the reaction in terms of integral reaction cross section, product internal state distributions, differential cross section, and rate constant. Fully converged and Coriolis coupled quantum mechanical calculations based on a time-dependent wave packet method have been performed at the state-to-state level on the ab initio electronic ground state potential energy surface (PES) constructed by Martinazzo et al.
