Serotonin 2 Receptors, Agomelatine, and Behavioral and Psychological Symptoms of Dementia in Alzheimer's Disease.

There are nearly 50 million Alzheimer's disease (AD) patients worldwide, 90% of whom develop behavioral and psychological symptoms of dementia (BPSD), which increase the mortality rate of patients, and impose an economic and care burden on families and society. As a neurotransmitter and neuromodulator, serotonin is involved in the regulation of psychoemotional, sleep, and feeding functions. Accumulating data support the importance of serotonin in the occurrence and development of BPSD.

Significance of Mycobacterium tuberculosis antigen expression in cerebrospinal fluid monocytes in diagnosing tuberculous meningitis.

Background: The aim of this study was to investigate the significance of positive expression of Mycobacterium tuberculosis, (MTB) antigen in the cerebrospinal fluid (CSF) monocytes in diagnosing tuberculous meningitis (TBM).

Materials And Methods: A total of 50 inpatients of TBM, 30 viral meningitis and 20 healthy controls were studied at the 1 st , 2 nd , and 4 th week during their treatment course. Immunohistochemical assay were used to detect early secreted antigenic target 6 (ESAT-6) positive cells, and positive cases were also observed.

[Cytological observation of anther abortion and starch distribution of a cytoplasm male sterile pepper (Capsicum annum L.)].

A cytoplasm male sterile pepper (Capsicum annum L.) was examined using cytochemical method to study its pollen abortion. Thick sections of both anthers of male sterility line 8214A and its maintainer 8214B at different stages were stained using Periodic Acid-Schiff's (PAS) reaction to detect starch distribution.
