Alzheimer’s disease (AD) is characterized by a robust inflammatory response elicited the accumulation and deposition of amyloid-β (Aβ) within brain. Aβ induces detrimental responses through toll-like receptors (TLRs) signaling pathway. Thymoquinone (TQ), main active constituent Nigella sativa oil, has been reported several previous studies for its potent anti-inflammatory effect. The aim this study to elucidate effect TQ in improving learning memory, using rat model AD induced combination...

Obesity is a continually growing pandemic leading to many diseases that affect the overall quality of life. The widely marketed Garcinia cambogia (GC) and Raspberry ketone (RK) were used in this study. Despite their known dietetic effect, however, metabolomic/signaling pathways involved effect are not fully elucidated. Hence, our study comprehends possible trajectories combination against obesity insulin resistance addition exploring merit.Adult male Wistar rats divided into 5 groups; viz.,...

Aim: Diabetic retinopathy causes loss of vision in adults at working-age. Few therapeutic options are available for treatment diabetic retinopathy. Carbamazepine (CARB), a widely used antiepileptic drug, was recently accounted its neuroprotective effect. Nerve growth factor (NGF) activates various cascades among which, PI3K/Akt/mTOR pathway has vital action NGF-mediated neuronal differentiation and survival. This study evaluated the effect CARB retina unveiled some underlying molecular...

Tribulus terrestris saponins (TTS) have been longley used as an overall tonic and recent studies showed they influence inflammatory conditions. We examined the ameliorative effect of a commercial formula saponin-rich extract TT in model dietary obesity female rats focusing on their ability to control burden, insulin resistance (IR), adipokine expression related reproductive system pathologies. Female were fed with high fat diet (HFD) for 14 weeks launch diet-induced obesity; assigned as:...

Although dysautonomia was documented in inflammatory bowel disease, with activation of the stress-related sympathetic system, role agonists/antagonists adrenergic receptors is not conclusive. Moreover, ulcerative colitis recently linked to dementia, but potential presenilin 1(PS1)/BACE-1/beta-amyloid (Aβ) axis has been evaluated. Hence, we investigated impact mirabegron (β3-agonist) and/or carvedilol (β1/β2 antagonist) on iodoacetamide-induced emphasis novel pathomechanism PS1/BACE-1/Aβ...

The first example of a new sub-family toxins (alpha-KTx20.1) from the scorpion Tityus trivittatus was purified, sequenced and characterized physiologically. It has 29 amino acid residues, three disulfide bridges assumed to adopt cysteine-stabilized alpha/beta scaffold with pI value 8.98. sequence identities all other known alpha-KTx are less than 40%. Its effects were verified using seven different cloned K(+) channels (vertebrate Kv1.1-1.5, Shaker IR hERG) expressed in Xenopus leavis...

Cardioprotective agents are compounds that provide heart protection and decrease cardiotoxicity incidence. Cardiotoxicity is a serious condition results in diminishing the heart's ability to pump blood throughout body can be developed into failure. Oxidative stress an important pathogenic event where generated reactive oxygen species (ROS) cause myocardial cellular destruction. Moreover, apoptosis, fibrosis, inflammatory cascades play major roles pathogenesis. Recently, much attention has...

OdK1 has 29 amino acids, six conserved cysteines and a pI value of 4.95. Based on multiple sequence alignments, was classified as α‐KTx 8.5. The pharmacological effects were studied different cloned K + channels (vertebrate Kv1.1‐Kv1.5 Shaker IR) expressed in Xenopus laevis oocytes. Interestingly, selectively inhibited the currents through Kv1.2 with an IC50 183 ± 3 nM but did not affect any other channels.
