Bupivacaine and Levobupivacaine are frequently used local anesthetic drugs in spinal anesthesia practice. Both agents have arrhythmic effects on the heart. However, there is no clear information about which agent is more arrhythmogenic.

The aim of this article is to investigate the effects of bupivacaine and its S (-)-enantiomer, levobupivacaine, on cardiac arrhythmias in patients.

The study included 40 patients scheduled for inguinal hernia surgery. Patients were randomly divided into the following two groups using a sealed envelope method Group I, the bupivacaine group (n = 20); and Group II, the levobupivacaine group (n = 20). The QT values were taken preoperatively and during the 10th of the spinal block, the 10th of the surgical incision, and the 10th postoperative minute. Additionally, systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), oxygen saturation (SO2), and heart rate (HR) values, in addition to motor block (Bromage scale) levels and durations, wereieve that levobupivacaine may be a better alternative to bupivacaine during clinical practice, particularly in patients with cardiac problems.A proteome is defined as a comprehensive protein set either of an organ or an organism at a given time and under specific physiological conditions and accordingly, the study of nervous system's proteomes is called Neuroproteomics. In the neuroproteomics process, various pieces of the nervous system are "fragmented" to understand the dynamics of each given sub-proteome in a much better way. Functional proteomics addresses the organisation of proteins into complexes, and formation of organelles from these multiprotein complexes that control various physiological processes. Current functional studies of neuroproteomics mainly talk about the synapse structure and its organisation, the major building site of the neuronal communication channel. The proteomes of synaptic vesicle, presynaptic terminal, and postsynaptic density, have been examined by various proteomics techniques. The objective of functional neuroproteomics is to solve the proteome of single neurons or astrocytes grown in cell cultures or from the primary brain cells isolated from tissues under various conditions; to identify set of proteins which characterize a specific pathogenesis; or to determine the group of proteins making up post-synaptic or pre-synaptic densities. It is very usual to try to solve a particular sub-proteome like the heatshock response proteome, or the proteome responding to inflammation. Posttranslational protein modifications alter their functions and interactions. The techniques to detect synapse phosphoproteome are available however, those for the analysis of ubiquitination and sumoylation, are under development.
Dementia is a neurodegenerative disorder majorly evidenced by cognitive impairment. learn more Although there are many types of dementia, the common underlying etiological factors in all the types are neuro-inflammation or ageing induced apoptosis. β-caryophyllene, a cannabinoid type-2 receptor agonist has reported to have promising neuroprotective effects in cerebral ischemia and neuro-inflammation.

In the present study, we evaluated the effects of β-caryophyllene, against animal models of dementia whose etiology mimicked neuro-inflammation and ageing.

Two doses (50 and 100 mg/kg of body weight) of β-caryophyllene given orally were tested against AlCl3-induced dementia in male Sprague Dawley (SD) rats using Morris water maze test. Subsequently, the effect of the drug was assessed for episodic memory in female SD rats using novel object recognition task in doxorubicin-induced neuro-inflammation and male SD rats for chemobrain model. Moreover, its effects were evaluated in D-galactose-induced mitochondrial dysfunct β-caryophyllene at 100 mg/kg protects against dementia induced by neuro-inflammation with no effect on neuronal aging induced by mitochondrial dysfunction.
Hence, we conclude that β-caryophyllene at 100 mg/kg protects against dementia induced by neuro-inflammation with no effect on neuronal aging induced by mitochondrial dysfunction.
The androgen receptor (AR) signaling functions is a critical driving force for the progression of prostate cancer (PCa) to bring about anti-prostate cancer agents, and AR has been proved to be an effective therapeutic target even for castration-resistant prostate cancer (CRPC).

In order to discover novel anti prostate cancer agents, we performed structural modifications based on the lead compounds T3 and 10e.

A set of 1-methyl- 1H-pyrazole-5-carboxamide derivatives were synthesized and evaluated for their inhibitory activities against both expressions of prostate-specific antigen(PSA) and growth of PCa cell lines.

Compound H24 was found to be able to completely block PSA expression at 10 µM, and showed prominent antiproliferative activity in both the LNCaP cell line (GI 50 = 7.73 µM) and PC-3 cell line (GI 50 = 7.07 µM).

These preliminary data supported a further evaluation of compound H24 as a potential agent to treat prostate cancer.

Autophagy plays a "double-edged sword" in the process of tumorigenesis, development and metastasis.

In this study, we explored the effect of PI3K/AKT/mTOR autophagy-related signaling pathway on regulating and controlling the invasion and metastasis of liver cancer cells by Bufalin.

The cell counting, migration, adhesion and invasion assay were used to evaluate the effect of Bufalin on cell proliferation, invasion and metastasis. The protein expression of PI3K/AKT/ mTOR signaling pathway were detected by the Western Blotting technique.

After inhibiting autophagy of HCC-LM3 cells, the inhibitory effect of Bufalin on adhesion, migration and invasion of HCC-LM3 cells was significantly enhanced. Synergistic inhibition was strongest when different autophagy inhibitors were combined with 3MA and CQ. After inhibiting autophagy, Bufalin significantly inhibited the protein expression of P-AKT, Cyclin D1, MMP- 2, MMP-9 and VEGF in HCC-LM3 cells. The protein expression of PTEN and E-Cadherin in HCC-LM3 cells was significantly increased.
