A Swin Transformer-based model for mosquito species identification.

Mosquito transmit numbers of parasites and pathogens resulting in fatal diseases. Species identification is a prerequisite for effective mosquito control. Existing morphological and molecular classification methods have evitable disadvantages.

Ovarian cancer metastasis to the breast 18 years after the initial diagnosis: A case report.

Rationale: Ovarian cancer often metastasizes, but it is unusual to transfer to the breast as an isolated mass. In particular, it is rare for patients to have breast metastases after 18 years of diagnosis of ovarian cancer. Therefore, accurate identification of ovarian cancer mammary gland metastasis can contribute to the treatment of the disease.

Evaluation of Residual Stress Distribution and Relaxation on In Situ TiB₂/7050 Al Composites.

Interior residual stresses induced by quenching may cause distortion during subsequent machining processes. Hence, various strategies have been employed to relieve the interior residual stress, such as stretching, post treatment, and other techniques. In this study, the stress distribution inside TiB₂/7050 Al composite extrusions was investigated and the effects of different methods on relieving the quenching-induced stress were compared.

[Effect of prepared Polygonum multiflorum on striatum extracellular acetylcholine and choline in rats of intracerebral perfusion with sodium azide].

Objective: To investigate the protection mechanism of prepared Polygonum multiflorum (PPMT) in rat brain with sodium azide (NaN3) perfusion.

Method: Rats were divided into six groups: control, model, PPMT, Duxil and PPMT + Duxil groups. The intracerebral microdialysis and high performance liquid chromatography-post column Immobilized enzyme reactor-electrochemical detection were used to continuously measure extracellular acetylcholine (ACh) and choline (Ch) levels in striatum of freely moving awake rats.

[Effect of prepared radix Polygoni multiflori on the elevation of extracellular hydroxyl radical in striatum of rats induced by intracerebral perfusion of 6-hydroxy dopamine].

Objective: To investigate the effect and mechanism of prepared Radix Polygoni Multiflori (RPM) on the elevation of extracellular hydroxyl radical in striatum of rats induced by intracerebral perfusion of 6-hydroxy dopamine (6-OHDA).

Methods: Cerebral microdialysis was used to establish the model. Hydroxyl radical was captured by salicylic acid, and 2,3-dihydroxy benzyl acid (2,3-DHBA) and 2,5-dihydroxy benzyl acid (2,5-DHBA) formed by hydroxyl radical in vital brain were measured by high performance liquid chromatography-electrochemical detector (HPLC-ED).

[Effect of tianma gouteng recipe on interfering LV and aortic hypertrophy in renovascular hypertension rats].

Objective: To investigate the effect of Tianma Gouteng recipe (TGR) on interfering left ventricular (LV) and aortic hypertrophy and tissue angiotensin II (Ang II) in rats with renovascular hypertension.

Method: The animal model of renovascular hypertension was used in this experiment. Hypertensive rats were randomly allocated into model group, Enalapril group and TGR group, and the drugs were used for 6 weeks continuously.

[Effects of Tianzhi Keli on extracellular acetylcholine and catecholamine levels in striatum of rats with neuromitochondrial impairment].

Objective: To investigate the effects of Tianzhi Keli (TZ) on acetylcholine (ACh) and catecholamine levels in striatum of rats with neuromitochondrial impairment, and try to find out the neuroprotective mechanism of TZ.

Method: The microdialysis and high performance liquid chromatography (HPLC)-post column Immobilized enzyme reactor (IMER)-electrochemical detection (ED) were used to establish a model of mitochondrial energy metabolism impairment which induced by perfusion with sodium azide (NaN3), and measure continuously the effects of TZ on extracellular ACh, choline (Ch) and catecholamine of model rats.

Result: After perfusion with NaN3, ACh, noradrenalin (NE), adrenaline (E), dopamine (DA), 3,4-Dihydroxyphenyl-aletic (DOPAC), and homovanillic acid (HVA) levels were decreased obviously (P < 0.

[Effects of tianma gouteng fang on transmitter amino acids in the hippocampus extracellular liquids in freely moving rats subjected to brain ischemia].

Objective: To observe the effects of Tianma Gouteng Fang (TGF) on the transmitter amino acids in the hippocampus extracellular liquids in freely moving rats subjected to incomplete brain ischemia.

Method: Hippocampus extracellular liquids was collected continuously by the microdialysis sampling technology in freely moving rats during pre-ischemia, incomplete ischemia and reperfusion periods induced by the occlusion and loose of both common carotid arteries. Each dialysate sample was assayed for GABA, Tau, Glu, Cys and Arg with HPLC-electrochemical detector.

[The measurement of tyrosine hydroxylase activity in the brain of conscious rats].

Objective: To set the measuring method of tyrosine hydroxylase activity in the brain of conscious rats.

Method: By using microdialysis and High Performance Liquid Chromatography-Electrochemical Detector system, the 3, 4-dihydrioxphenylalanine (DOPA) formation in the striatum of 6-hydroxdopamine-pretreated rats during infusion of an L-aromatic amino-acid decarboxylase inhibitor (NSD1015) was monitored.

Result: The absence of DOPA in dialysates of 6-hydroxdopamine-pretreated rats, the measurable DOPA and the steady decreasing of 3,4-dihydroxyphenylacetic acid(DOPAC) during infusion of NSD1015 and the disappearance of DOPA after administration of alpha-methyl-rho-tyrosine indicated that the dialyzed DOPA was derived from dopaminergic nerve terminals.

[The effect of shourong compound formula on levels of dopamine and its metabolites in brain of Parkinson's disease mice induced by reserpine].

Objective: To investigate the effect of Shourong compound formula on treating Parkinson's disease.

Method: Parkinson's disease model mice induced by reserpine was used and by HPLC-ED the levels of Dopamine (DA) and its metabolites were determined.

Result: Madopar could increase the levels of DA in brain of PD mice.
