An Uncommon Clinical Mystery: Systemic Lupus Erythematosus Masquerading as Aseptic Meningitis in a Male Patient.

Systemic lupus erythematosus (SLE) is an intricate autoimmune disease characterized by its impact on various organ systems, presenting with a wide range of clinical manifestations such as hematologic, neuropsychiatric, mucocutaneous, serosal, musculoskeletal, immunologic, cardiac, pleuropulmonary, and renal symptoms. Although its etiology is primarily autoimmune, various triggers, such as pregnancy, certain drugs, and infections, can result in "flares" with frequent relapses. Although more common in females, SLE is not uncommon in males, with a significant proportion experiencing a high disease burden.

Kocuria rosea Sepsis in an Immunocompromised Patient: A Case Report.

species, classified within the phylum , class , order  family , are Gram-positive coccoid bacteria. They bear morphological resemblance to and which often leads to misidentification and oversight as contaminants, given their presence as normal flora on human and animal skin and mucous membranes. Accurate identification of these organisms typically relies on automated systems such as MALDI-TOF-MS, Vitek-2 System, and 16S rRNA studies.

Anti-tubercular treatment-induced granulomatous acute interstitial nephritis.

This case emphasizes the value of meticulous observation and regular follow-up of patients receiving rifampicin therapy. The prognosis for complete improvement in renal function in such cases was excellent, with prompt recognition and discontinuation of rifampicin. Teaching patients about these possible adverse effects and encouraging immediate reporting of signs and symptoms are likely to be beneficial because acute kidney injury can manifest itself very quickly after rifampicin is started.

On evaluation, she was found to have an oral thrush with leucocytosis. Initial blood and urine cultures were sterile, and ultrasonography revealed hypoechoic lesions in the left lobe of the liver.

An Unusual Case of Alcoholic Liver Disease Associated with Secondary IgA Vasculitic Nephritis presenting as Rapidly Progressive Glomerulonephritis.

IgA nephropathy (IgAN) is a fairly common association with alcoholic liver disease. However, IgA vasculitis (IgAV) is quite an uncommon association with alcoholic liver cirrhosis and only a handful of cases have been reported in literature. Secondary IgAN usually presents in a docile manner, progressing slowly in about 5-25 years.

Prevalence and Risk Factors of Heart Failure with Preserved Ejection Fraction in Middle-Aged Maintenance Haemodialysis Patients on a Twice-Weekly Schedule: Experience from a Single Indian Centre.

Prospects for Prostate Cancer Chemotherapy: Cytotoxic Evaluation and Mechanistic Insights of Quinolinequinones with ADME/PK Profile.

The evaluation of in vitro biological activity of several previously reported quinolinequinones () against 60 human cancer cell lines (NCI-60) used by the National Cancer Institute's Developmental Therapeutics Program (DTP) contributed to our earlier research on possible anticancer and/or antibacterial agents. Of interest, NCI-60 screening revealed that two quinolinequinones ( and ) significantly reduced the proliferation of several cancer genotypes. Following the administration of a single dose and five additional doses, all quinolinequinones demonstrated a significant inhibitory effect on the growth of leukemia and other cancer cell lines.

A chemical modification of a peroxisome proliferator-activated receptor pan agonist produced a shift to a new dual alpha/gamma partial agonist endowed with mitochondrial pyruvate carrier inhibition and antidiabetic properties.

New analogs of the PPAR pan agonist AL29-26 encompassed ligand (S)-7 showing potent activation of PPARα and -γ subtypes as a partial agonist. In vitro experiments and docking studies in the presence of PPAR antagonists were performed to help interpretation of biological data and investigate the main interactions at the binding sites. Further in vitro experiments showed that (S)-7 induced anti-steatotic effects and enhancement of the glucose uptake.

Determination of Trace Organic Contaminant Concentration via Machine Classification of Surface-Enhanced Raman Spectra.

Surface-enhanced Raman spectroscopy (SERS) has been well explored as a highly effective characterization technique that is capable of chemical pollutant detection and identification at very low concentrations. Machine learning has been previously used to identify compounds based on SERS spectral data. However, utilization of SERS to quantify concentrations, with or without machine learning, has been difficult due to the spectral intensity being sensitive to confounding factors such as the substrate parameters, orientation of the analyte, and sample preparation technique.
