Dexamethasone affects the chemotaxis and phagocytic activity of neutrophils for boar spermatozoa and the quality of liquid preserved boar semen in vitro.

This study aimed to investigate the effect of dexamethasone (DEX) on chemotaxis and phagocytic activity of neutrophils for spermatozoa and semen quality of preserved boar semen. The different concentrations of dexamethasone were added to boar semen dilutions to detect its effects on the chemotaxis of neutrophils and phagocytosis of neutrophils and sperm motility sperm malformation rate, plasma membrane integrity, mitochondrial activity, and spermatozoa motility parameters. The study results showed that the experimental groups of DEX significantly inhibited the phagocytosis and chemotaxis of PMNs for spermatozoa.

Superhydrophobic E-textile with an Ag-EGaIn Conductive Layer for Motion Detection and Electromagnetic Interference Shielding.

As as emerging innovation, electronic textiles have shown promising potential in health monitoring, energy harvesting, temperature regulation, and human-computer interactions. To access broader application scenarios, numerous e-textiles have been designed with a superhydrophobic surface to steer clear of interference from humidity or chemical decay. Nevertheless, even the cutting-edge electronic textiles (e-textiles) still have difficulty in realizing superior conductivity and satisfactory water repellency simultaneously.

Pilot study of new diagnostic criteria for middle cerebral artery stenosis by transcranial Doppler.

Background And Purpose: Current criteria for middle cerebral artery (MCA) stenosis by transcranial Doppler were mainly based on the flow velocity acceleration, ignoring other useful parameters. We tested the accuracy of new criteria using magnetic resonance angiography (MRA) as the confirmative method.

Methods: A compositive score for each MCA was calculated according to following parameters: Velocity Scale (score 0-6 for peak systolic velocity <140 to > or = 300 cm/second), Hemodynamic Scale (score 0-5 for diffuse or focal velocity increase; score 0-6 for differences between bilateral MCA; score 17 for damping velocity), and Spectrum Scale (score 0-2 for normal spectrum, turbulence, and musical murmurs).

Prevalence and risk factors of middle cerebral artery stenosis in asymptomatic residents in Rongqi County, Guangdong.

Background: Intracranial atherosclerosis is the commonest vascular lesion for ischemic stroke in Asians. Most research on risk factors for middle cerebral artery (MCA) stenosis has been conducted in symptomatic patients with ischemic stroke or transient ischemic attack. The present study aimed to investigate risk factors for MCA stenosis in an asymptomatic population in Rongqi County in Southern China.

Hyperhomocysteinemia is a risk factor of middle cerebral artery stenosis.

Purpose: Hyperhomocysteinemia (HHcy) is considered to be an independent risk factor for atherosclerosis. We aimed to determine the relation between Hcy and cerebral artery stenosis in a large Chinese population.

Methods: We present data concerning 2,500 residents.

[The analysis of plasma homocysteine among 1020 residents in community].

Objective: To study the plasma homocysteine (Hcy) distributive characteristics in different sex and age groups of the community residents in Guangdong, and to analyze its associated factors as well as its effects on cerebral artery stenosis.

Methods: In this study, we presented data concerning 2500 residents who had undergone a systematic health checkup,including clinical and biologic examinations. Plasma was saved from 1020 residents who were asymptomatic but having TCD examination.

[Analysis on data gathered from transcranial Doppler among 1500 normal adults community].

Objective: To study the rates of receiving doppler signal, flow velocity of cerebral artery and the relationship between flow velocity,age and gender in normal adults in China.

Methods: A total of 1500 normal residents at the community level in Guangdong province were examined, using transcranial doppler. Data was gathered and analyzed.
