Digital gangrene without sclerodactyly in the presence of anticentromere antibodies: A unique presentation of scleroderma.

Peripheral vascular disorders associated with anti-centromere antibody (ACA) present generally with sclerodactyly in connective tissue disorders (CTD). It is unusual for ACA-associated digital necrosis to develop without preexisting raynaud's phenomena or vascular risk factors. We report a novel case of a 60-year-old non-smoker, non-diabetic woman with ACA and isolated finger necrosis without any other features of CTD.

Limitations of effective medium models for tissue phantoms in the THz frequency range.

The absorption of terahertz (THz) radiation by water molecules facilitates its application to several biomedical applications such as cancer detection. Therefore, it is critical for the THz technologies to be characterised with water content in a sample. In this paper, we analyse gelatine phantoms in the THz frequency range, with continuously varying hydration levels as they dry over time.

Utilization of MALDI-TOF MS in the etiological diagnosis of deep-seated anaerobic bacterial infections.

Purpose: Deep-seated abscesses can be caused by a wide array of bacteria in various anatomical sites, the precise identification of which is crucial for implementing organism-specific treatments which can reduce morbidity and mortality. MALDI-TOF MS is a powerful proteomic method for the swift and accurate identification of anaerobic organisms. The aim of this study was to investigate deep-seated infections by MALDI-TOF MS (in comparison to VITEK®2 ANC ID card and phenotypic biochemical tests) and to determine the susceptibility pattern of identified microorganisms.

Pulmonary cryptococcosis in chronic kidney disease.

Pulmonary cryptococcosis is a fungal infection caused by Cryptococcus species, with Cryptococcus neoformans being the most common agent, affecting the lungs. While it commonly occurs in immunocompromised individuals, such as those with HIV/AIDS or undergoing immunosuppressive therapy, its presentation in patients with chronic kidney disease (CKD) is relatively rare. However, it should be considered in the differential diagnosis of respiratory infections in patients with CKD, particularly in the context of immunosuppression.

Aquatic whispers: Decoding skin manifestation of Aeromonashydrophila.

WHONET software was utilised to capture and analyse the changes in the interpretation of disc diffusion method, following updates to CLSI M100 documents in comparison to previous editions.

Paeniclostridium sordellii causing liver abscess: A rare case report in India.

Paeniclostridium sordellii, an anaerobic bacterium, causes hepatic infections in alcoholics and post-surgery (liver transplantation). While liver and brain abscesses are rare, drainage procedures and targeted antibiotic therapy assisted by early microbiological diagnosis have reduced mortality rates. We report a rare case of pyogenic liver abscess caused by Paeniclostridium sordellii in India, the early diagnosis of which has led to life saving outcome for the patient.

Quality assurance of SARS-CoV-2 testing laboratories during the pandemic period in India - An experience from a designated provider laboratory.

Methods: Adults with a diagnosis of moderate-to-severe UC or CD for ≥6 months and experience of bowel urgency in the past 6 months were included.

Facial cutaneous phaeohyphomycosis in an immunocompetent individual.

Fungal infection is a rare condition in immunocompetent individuals, and it is associated with high rates of morbidity and mortality. We report on a case of cutaneous phaeohyphomycosis in healthy 25-year-old man. Based on the clinical findings, the case was first thought to be cervico-facial actinomycosis, but Alternaria was identified on the culture after debridement.

Blood borne infections and Hepatitis B virus immunization levels among medical students in India.

Background: Medical students are actively involved in direct patient care during their training and subsequent medical practice, making them susceptible to acquiring blood-borne pathogens, including HBV. This study aimed to assess the occurrence of blood-borne infections and the Hepatitis B immunization status among medical students. Furthermore, it sought to identify gaps in risk assessment for blood-borne pathogens among medical students at a Medical College in New Delhi.

DNMT1 downregulation as well as its overexpression distinctly affect mostly overlapping genes implicated in schizophrenia, autism spectrum, epilepsy, and bipolar disorders.

Data on schizophrenia (SZ), epilepsy (EPD) and bipolar disorders (BPD) suggested an association of DNMT1 overexpression whereas certain variants of the gene were predicted to result in its increased expression in autism spectrum disorder (ASD). In addition, loss of DNMT1 in frontal cortex resulted in behavioral abnormalities in mice. Here we investigated the effects of increased as well as lack of DNMT1 expression using neurons as a model for abnormal neurogenesis and 10,861 genes showing transcript level dysregulation in datasets from the four disorders.

Immunogenicity and protective efficacy of an inactivated Newcastle disease virus vaccine encapsulated in poly-(lactic-co-glycolic acid) nanoparticles.

An immunization experiment was conducted in specific pathogen-free chickens with the inactivated Newcastle disease virus (NDV) vaccine encapsulated in the poly-(lactic-co-glycolic) acid (PLGA) nanoparticles (NP) to evaluate its immunogenicity and protective efficacy. The NDV vaccine was prepared by inactivating one virulent Indian strain of NDV belonging to Genotype VII by using beta-propiolactone. PLGA nanoparticles encapsulating inactivated NDV were prepared by the solvent evaporation method.
