    In the title compound, C13H16N2O4, an intra­molecular N—H⋯O hydrogen bond generates an S(6) ring. The mol­ecule adopts an E configuration with respect to the central C=N double bond. In the crystal, symmetry-related mol­ecules are connected into chains along [010] via weak C—H⋯N hydrogen bonds. The crystal structure is further stabilized by weak C—H⋯π inter­actions

    The Influence of Emotional States on Short-Term Memory Retention by Using Electroencephalography (EEG) Measurements: A Case Study

    The electroencephalogram (EEG) is a non-invasive test that records the electrical activity of the brain as wave patterns generated by various brain structures. The electrical activity is recorded from the scalp surface after being picked up by metal electrodes (small metal discs) and conductive media. This study explored how emotions can impact short-term memory retention, and thus the process of learning, by analyzing five mental tasks: relaxation, memorization of ten words, memorization of ten two-digit numbers, visual exposure to emotional stimuli, and recall of the 10 words and 10 numbers. The word list contained ten words as five event-related (directly related to the type of emotion triggered) and five not event-related words. The visual task was separated into three categories corresponding to the type of image extracted from the public domain International Affective Picture System (IAPS) library, which in turn correspond to three emotional states assumed to be evoked by them: neutral, negative (e.g. sadness), and positive (e.g. happiness). Event-related potentials (ERP) were measured by EEG with the ANT Neuro system. The ASA software and EEGLab were utilized for the analysis of ERPs in five EEG bands: Delta (0-3.9Hz), Theta (4-7.9Hz), Alpha (8-12.9Hz), Beta (13-30 Hz), and Gamma (31-50 Hz). Eleven participants (ten males and one female between 20 and 25 years old) were included in this case study. To date, no other studies have been reported to use EEG measurements in the evaluation of the influence of emotional states on short-term memory retention

    In the title compound, C11H11N5OS, the pyrazole ring is approximately planar, with a maximum deviation of 0.010 (2) Å. The dihedral angles between the benzene ring and the pyrazole and carbothio­amide groups are 5.42 (9) and 10.61 (18)°, respectively. An intra­molecular N—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol­ecules are connected by inter­molecular N—H⋯O and C—H⋯S hydrogen bonds, forming R 2 2(12) ring motifs. In addition, there is a π–π stacking inter­action [centroid–centroid distance = 3.5188 (11) Å] between the pyrazole and benzene rings. These inter­actions link the mol­ecules into infinite chains along [001]

    There is a wide range of importance for appearance in present era. Psoriasis is chronic disorder which is commonly encountered in day to days clinical practices. It is one of the burning issue having social importance. Increased stress and life style are main predisposing factor which is accounting for wide spared prevalence of this disease. Usually10-15% cases present before general practitioners are pertaining to skin diseases. Due to altered life style, lack of physical exercise, unhygienic, mental stress, over eating, skin diseases are commonly observed. We can observe many diseases popping up especially due to mental stress i.e., Manasa Vikriti. There is Samavaya Sambandha between Tvacha and Manas (Chetah Samavayi). Most of the Tvak Vikaras are psychologically agonising and have negative impact on quality of life. Here it is important to remember the citation of Acharya Charaka regarding the relationship between the Tvacha and Manas, Tvacha is considered as Chetah Samvayi i.e., the skin has an eternal relationship with Manas (psyche/mind). The knowledge of Nidana is helpful for the proper diagnosis, prevention of disease and treatment also. Thus to treat any Tvak Gata Vikara, Bhishak should consider the skin ailment as well as condition of Manas. This paper highlights a case study of stress related Kitibha Kusta (Psoriasis) treated with Shodhana Chikitsa.
