Elemental Mercury Poisoning by Self-Injection - A Report of Two Cases.

Injection of mercury into the upper limb is a rare method of self-harm. We report two patients with varied clinical presentations - a 19-year-old male student who injected himself with mercury extracted from a sphygmomanometer bulb and reported to our emergency department 24 hours after the event and a 34-year-old industry worker who presented 2 years after injecting himself with elemental mercury. The management of mercury poisoning is described along with a brief review of literature.

VAMP2 regulates phase separation of α-synuclein.

α-Synuclein (αSYN), a pivotal synaptic protein implicated in synucleinopathies such as Parkinson's disease and Lewy body dementia, undergoes protein phase separation. We reveal that vesicle-associated membrane protein 2 (VAMP2) orchestrates αSYN phase separation both in vitro and in cells. Electrostatic interactions, specifically mediated by VAMP2 via its juxtamembrane domain and the αSYN C-terminal region, drive phase separation.

Cyanoacrylate vs. sutures in clean and clean-contaminated surgical wounds - a randomised control study.

Objectives: Various techniques of closure of surgical incisions have been described ranging from various suture materials, staples and tapes to adhesive compounds. Cyanoacrylate is an adhesive compound available for surgical incision closure. Although sutures have been the preferred universal choice for surgical incision closure, glue is gaining popularity in specific places like pediatric injuries, facial injuries, laparoscopic incision closure, etc.

Neuronal exosomal miRNAs modulate mitochondrial functions and cell death in bystander neuronal cells under Parkinson's disease stress conditions.

Parkinson's Disease (PD) is a chronic neurodegenerative disorder characterized by progressive loss of midbrain dopaminergic neurons in the substantia nigra part of the brain. Pathology spread to numerous brain regions and cell types suggests that intercellular communication is essential to PD progression. Exosomes mediate intercellular communication between neurons, glia, and other cell types throughout PD-relevant brain regions.

Role of NFE2L1 in the Regulation of Proteostasis: Implications for Aging and Neurodegenerative Diseases.

A hallmark of aging and neurodegenerative diseases is a disruption of proteome homeostasis ("proteostasis") that is caused to a considerable extent by a decrease in the efficiency of protein degradation systems. The ubiquitin proteasome system (UPS) is the major cellular pathway involved in the clearance of small, short-lived proteins, including amyloidogenic proteins that form aggregates in neurodegenerative diseases. Age-dependent decreases in proteasome subunit expression coupled with the inhibition of proteasome function by aggregated UPS substrates result in a feedforward loop that accelerates disease progression.

Protective Effects of Polyphenol-Rich Extracts against Neurotoxicity Elicited by Paraquat or Rotenone in Cellular Models of Parkinson's Disease.

Parkinson's disease (PD) is a neurodegenerative disorder involving motor symptoms caused by a loss of dopaminergic neurons in the substantia nigra region of the brain. Epidemiological evidence suggests that anthocyanin (ANC) intake is associated with a low risk of PD. Previously, we reported that extracts enriched with ANC and proanthocyanidins (PAC) suppressed dopaminergic neuron death elicited by the PD-related toxin rotenone in a primary midbrain culture model.

Plastic Surgery Practice during COVID Times.

 COVID-19 has affected plastic surgeons like never before. We conducted an all-India survey to find how the practice was affected among public/private sector, reconstructive/aesthetic practice, and consultants/residents. We have proposed some solutions to the identified problems, which are supported by previous literature.

Shining a light on autophagy in neurodegenerative diseases.

Small-molecule modulators of autophagy have been widely investigated as potential therapies for neurodegenerative diseases. In a recent issue of JBC, Safren et al. described a novel assay that uses a photoconvertible fusion protein to identify compounds that alter autophagic flux.

Its Not about the Destination, Its about the Journey-Plotting 50 Years of Changing Clinical Trends in Plastic Surgery in a Public Sector Teaching Hospital.

The year 2019 marked the 50th anniversary of plastic surgery department of our institution. We present an audit to plot the changing clinical trends in our work in the past five decades. A single-center retrospective cohort study based on the department demographics was performed and compared across the decades from 1969 to 2019.

Alpha-Synuclein Is a Target of Fic-Mediated Adenylylation/AMPylation: Possible Implications for Parkinson's Disease.

During disease, cells experience various stresses that manifest as an accumulation of misfolded proteins and eventually lead to cell death. To combat this stress, cells activate a pathway called unfolded protein response that functions to maintain endoplasmic reticulum (ER) homeostasis and determines cell fate. We recently reported a hitherto unknown mechanism of regulating ER stress via a novel post-translational modification called Fic-mediatedadenylylation/AMPylation.

Distribution of antibiotic resistance and virulence factors among the bacteria isolated from diseased .

Considering the emerging concern with the antimicrobial resistance (AMR) evolution, the study has been designed to identify the antibiotic resistance and virulence properties of culturable bacteria isolated from the diseased fish . This has resulted in the purification of 18 morphologically distinct bacterial isolates which were identified by both biochemical and molecular methods. Antibiotic resistance analysis showed the resistance of these isolates to multiple antibiotics and remarkable evolution of AMR.

Genomic amplification of BCR-ABL1 fusion gene and its impact on the disease progression mechanism in patients with chronic myelogenous leukemia.

Identification of BCR-ABL1 fusion gene amplification status is critically important in the effective management of chronic myelogenous leukemia (CML) patients. Earlier reports suggested that overexpression of BCR-ABL1 either through amplification of BCR-ABL1 fusion gene or by the up regulation of BCR-ABL1 transcript level might be an early phenomenon in the establishment of IM resistance and disease evolution in CML. In the current study, we performed dual color dual fusion locus specific BCR/ABL1 FISH analysis along with karyotype analysis using GTG banding (G-banding using trypsin and Giemsa) technique in 489 patients with different clinical stages of CML at diagnosis or during the course of the disease to unravel the spectrum of BCR-ABL1 fusion gene amplification status.

Prognostic Implications of Derivative Chromosome 9 Deletions in Patients with Advanced-Stage Chronic Myelogenous Leukemia.

Elucidation of cryptic BCR/ABL1 gene rearrangement is exceptionally important in the clinical diagnosis and prognosis of chronic myelogenous leukemia (CML). Previous reports indicated an adverse prognostic effect of atypical BCR/ABL1 gene rearrangements with submicroscopic ABL1-BCR deletions on derivative chromosome 9 [der(9)] in CML patients. Dual color dual fusion locus-specific BCR/ABL1 fluorescent in situ hybridization (FISH) analysis together with G-banding using trypsin and Giemsa (GTG banding) was performed in 489 patients at different stages of CML to investigate the spectrum of BCR/ABL1 gene rearrangements.
