The classification of a pre-processed fMRI dataset using functional connectivity (FC)-based features is considered a challenging task because of the set of high-dimensional FC features and the small dataset size. To tackle this specific set of FC high-dimensional features and a small-sized dataset, we propose here a conditional Generative Adversarial Network (cGAN)-based dataset augmenter to first train the cGAN on computed connectivity features of NYU dataset and use the trained cGAN to generate synthetic connectivity features per category. After obtaining a sufficient number of connectivity features per category, a Multi-Head attention mechanism is used as a head for the classification.

There is, until now, not a gold standard test using which an ADHD expert can differentiate between an individual with ADHD and a healthy subject, making accurate diagnosis of ADHD a challenging task. We are proposing a Knowledge Distillation-based approach to search for discriminating features between the ADHD and healthy subjects.

Accurate identification of autistic patients is considered a challenging task in the domain of brain disorder science. To address this problem, we have proposed a three-stage feature selection approach for the classification of ASD on the preprocessed Autism Brain Imaging Data Exchange (ABIDE) rs-fMRI Dataset.

Background: Thrombocytopenia is often seen in the patients of malaria infected with Plasmodium vivax. We studied patients admitted in hospital having coexisting thrombocytopenia and malaria, and recorded the response to anti-malarial therapy.
Methods: In this cross-sectional descriptive study, a total of 120 patients admitted in medical ward with Plasmodium vivax malaria and co-existing thrombocytopenia were studied.
A series of N-(2-anilino-pyridyl) linked 2-amino benzothiazoles (4a-n) and [1,2,4]triazolo [1,5-b]benzothiadiazine conjugates (5a-j) have been designed, synthesized and evaluated for their antiproliferative activity. Some of these compounds (4h-k, 4n, and 5e) have exhibited potent cytotoxicity specifically against human leukemia HL-60 cell lines with IC(50) values in the range of 0.08-0.

In the current report, we prospectively examined the hypothesis that asymptomatic patients with high CK (>or=250 but <2500 IU/L) tolerate statins well at doses reducing LDLC to target, less than 100 mg/dL, without development of myalgia-myositis. We assessed outcomes of 3 groups of patients referred to us because of asymptomatic high CK (>or=250 but <2500 IU/L)--1 group (n = 29) on statins at referral and continued on statins, 1 group (n = 20) not on statins and started on statins, and 1 group (n = 19) not on statins and not given statins--all restudied 1 month after entry and then every 3 months.
