Acidic Environment Induces Pyroptosis of NLRP3 Inflammatory Vesicle-Mediated Nucleus Pulposus Cells Through Up-Regulation of POSTN Expression

Int. j. morphol; 41 (6), 2023
SUMMARY: Intervertebral disc degeneration (IVDD) is induced by nucleus pulposus (NP) dysfunction as a result of massive loss of NP cells. It has been reported that the acidic microenvironment of the intervertebral disc (IVD) can induce NP cell pyroptosis, and that up-regulation of periostin (POSTN) expre...

Time - sensitive effects of Zhuang medicated thread moxibustion on estrogen level in female perimenopausal model rats

The present study was conducted to ascertain the estrogenic effect of Zhuang Medicated Thread Moxibustion (ZMTM) and explore its time - sensitive impact on estradiol (E2) in female perimenopausal rats. 40 female rats were randomized into four gr oups: the control, model, ...

The Effects of White Tea (Camellia Sinensis) and Infliximab Against Cisplatin- Induced Testicular Damage via Oxidative Stress and Apoptosis

Int. j. morphol; 41 (5), 2023
SUMMARY: Cisplatin (Cis) is an important chemotherapeutic agent used in cancer treatment. Males exposed to Cis were reported to exhibit testicular toxicity. Cis-induced testicular toxicity is mediated by oxidative stress, inflammation, testosterone inhibition and apoptosis. Accordingly, this study was co...

Uncontrolled Diabetes with Underlying Structural Changes in the Atrioventricular Node

Int. j. morphol; 41 (4), 2023
SUMMARY: Diabetic cardiomyopathy, characterized by diabetes mellitus (DM) -induced cardiac muscular abnormalities, is a strong inducer of impaired cardiac contraction and arrhythmia. Atrioventricular block, a serious type of arrhythmia resulting from interruption of cardiac impulse conduction via the atr...

Altered Chief Cell Morphology in the Gastric Gland of Streptozotocin-Diabetic Rats

Int. j. morphol; 41 (4), 2023
SUMMARY: Diabetes mellitus (DM) is a metabolic disorder with rising incidences worldwide. Gastric symptoms of DM have been reported, including nausea, vomiting, bloating, and epigastric pain. Moreover, acute to chronic gastritis and atrophic gastritis occur in DM can affect the chief cells of the gastric...

The Role of MMP-9 in Regulating Degradation of the Splenic Microvascular Basement Membrane Induced by High Altitude Hypoxia

Int. j. morphol; 41 (4), 2023
SUMMARY: To investigate changes of MMP-9 in the rat spleen and hypoxia-induced microvascular basement membrane under high altitude hypoxia. Thirty male specific pathogen-free Sprague Dawley rats were randomly divided into control and hypoxia groups, with 15 rats in each group. The rats in the control gro...

Changes in the Craniomaxillofacial Growth and Development of Sprague Dawley Rats Subjected to Permanent Experimental Unilateral Nasal Obstruction

Int. j. morphol; 41 (4), 2023
SUMMARY: Breathing is considered a vital function dependent on factors such as adequate permeability of the nasal route, which is linked to physiological functions, intellectual processes, and craniofacial growth. The aim of this study was to determine the changes in the craniomaxillofacial growth and bo...

Localization of Diacylglycerol Kinase ζ in the Kidney of Adult Rats: Its Dominant Expression in Collecting Tubules and its Selective Lack in Proximal Tubules

Int. j. morphol; 41 (3), 2023
SUMMARY: Diacylglycerol kinase (DGK) exerts balancing the intracellular level between two-second messengers, diacylglycerol and phosphatidic acid, by its phosphorylation activity. DGK ζ is often localized in cell nuclei, suggesting its involvement in the regulation of intranuclear activities, includ...

HDAC2 Inhibits Hippocampal Neurogenesis and Impairs the Cognitive Function in Prenatally Stressed Adult Offspring

Int. j. morphol; 41 (3), 2023
SUMMARY: The objective of this study was to investigate the mechanism of prenatal stress on the cognitive function of offspring, and clarify the change of histone deacetylase 2 (HDAC2) expression in hippocampal neurons of offspring. 16 pregnant SD rats were randomly divided into control group and stress ...

Morphological Effects of Cigarette Smoking on Respiratory System and Related Functions Based on AQPs Expression

Int. j. morphol; 41 (2), 2023
SUMMARY: A great deal of attention of air pollution on respiratory health is increasing, particularly in relation to haze days. It is that exposure to cigarette smoke augments the toxicity of common air contaminants, thereby increasing the complexity of respiratory diseases. Although there are various me...
