Leishmaniasis is a worldwide health problem, highly endemic in developing countries. Among the four main clinical forms of the disease, visceral leishmaniasis is the most severe, fatal in 95% of cases. The undesired side-effects from first-line chemotherapy and the reported drug resistance search for effective drugs that can replace or supplement those currently used in an urgent need. Aminoguanidine hydrazones (AGH's) have been explored for exhibiting a diverse spectrum of biological activities, in particular the antileishmanial activity of MGBG. The bioisosteres thiosemicarbazones (TSC's) offer a similar biological activity diversity, including antiprotozoal effects against Leishmania species and Trypanosoma cruzi.
Considering the impact of leishmaniasis worldwide, this work aimed to design, synthesize, and perform a screening upon L. chagasi amastigotes and for the cytotoxicity of the small "inhouse" library of both AGH and TSC derivatives and their structurally-related compounds.
A set of AGH's (3-7est hits for in vivo experiments.Bone metastases are a common source of malignancy in the skeleton and occur much more often than primary bone cancer. Several works were being performed to identify early markers for bone metastasis and novel drug targets to improve patients' quality of life. As some concerns exist with the [18F]sodiumfluoridein positron emission tomography (PET) bone imaging, there has been an increase in the number of targeted radiopharmaceutical markers for bone metastases imaging in its competitor, 68Ga. Since 18F properties are superior to those of 68Ga, there is a distinct motivation for developing 18F radiopharmaceuticals for bone metastases imaging.The article has been withdrawn at the request of the editor of the journal Current Diabetes Reviews, due to incoherent content.Bentham Science apologizes to the readers of the journal for any inconvenience this may have caused.The Bentham Editorial Policy on Article Withdrawal can be found at https//benthamscience.com/editorial-policies-main.php.

Cysteine is a versatile amino acid for selective chemical modification of proteins with both chemical and biological innovations, which plays a key role in different organic reactions.
Chemical modification of proteins is a rapidly expanding area in chemical biology. Selective installation of biochemical probes has led to a better understanding of natural protein modification and macromolecular function. In other cases, such as chemical alterations, the protein function has entirely changed. This review paper considers the organic reaction of cysteine, the reactivity of this α-amino acid containing sulfur, and several methodologies are also discussed. Herein, we focused on the reaction of cysteine and its application in organic synthesis, which includes addition, condensation, substitution, oxidation, and ring-opening reactions.
Hence monitoring of cysteine is pivotal through the preparation of some fluorescent probes to detect cysteine in high sensitivity. Also, a bibliometric analysis was carried out using Web of Science and Scopus databases that demonstrated significant contributions being observed in organic synthesis. Analysis of keywords revealed that research hotspots were cysteine, sensor, unclassified drug, and amino acid.
Therefore, it seems that future research focuses on using cysteine amino acids in various fields as natural products and organic reactions. This focused review highlights the enduring utility of cysteine in protein modification and sensor preparation, with a special focus on recent innovations in chemistry and biology associated with such modifications.

Here, we delineate the intricate relationship between breast cancer and COVID-19. Breast cancer and COVID-19 share the involvement of common comorbidities, hormonal signalling pathways, gender differences, rennin- angiotensin system (RAS), angiotensin-converting enzyme-2 (ACE-2), transmembrane protease serine 2 (TMPRSS2) and dipeptidyl peptidase-IV (DPP-IV). We also shed light on the possible effects of therapeutic modalities of COVID-19 on breast cancer outcomes. Briefly, we conclude that breast cancer patients are more susceptible to COVID-19 in comparison with their normal counterparts. this website Women are more resistant to the occurrence and severity of COVID-19. Increased expressions of ACE2 and TMPRSS2 are correlated with occurrence and severity of COVID-19, but higher expression of ACE2 and lower expression of TMPRSS2 are prognostic markers for overall disease free survival in breast cancer. The ACE2 inhibitors and ibuprofen therapies for COVID-19 treatment may aggravate the clinical condition of breast cancer patients through chemo-resistance and metastasis. Most of the available therapeutic modalities for COVID-19 were also found to exert positive effects on breast cancer outcomes. Besides drugs in clinical trend, TMPRSS2 inhibitors, estrogen supplementation, androgen deprivation and DPP-IV inhibitors may also be used to treat breast cancer patients infected with SARS-CoV-2. However, drug-drug interactions suggest that some of the drugs used for the treatment of COVID-19 may modulate the drug metabolism of anticancer therapies which may lead to adverse drug reaction events.
While identifying Alzheimer's Disease (AD) in its early stages is crucial, traditional neuropsychological tests tend to lack sensitivity and specificity for its diagnosis. Neuropsychological studies have reported visual processing deficits of AD, and event-related potentials (ERPs) are suitable to investigate pre-attentive processing with superior temporal resolution.
This study aimed to investigate visual attentional characteristics of adults with AD, from pre-attentive to attentive processing, using a visual oddball task and ERPs.
Cognitively normal elderly controls (CN) and patients with probable AD (AD) were recruited. Participants performed a three-stimulus visual oddball task and were asked to press a designated button in response to the target stimuli. The amplitudes of 4 ERPs were analyzed. Mismatchnegativity (vMMN) was analyzed around the parieto-occipital and temporo-occipital regions. P3a was analyzed around the fronto-central regions, whereas P3b was analyzed around the centro-parietal regiontive ERPs can be induced by passive exposure to infrequent stimuli.The socio-economic burden of renal disease is enormous due to the unavailability of effective treatment to cure it. High risk patients have only two costly options in chronic renal disease, dialysis and renal replacement therapy (RRT). RRT has limitations of the organ donor, and ethical concerns are also associated with it. The Wnt/beta-catenin pathway is highly conserved and active during embryogenesis in early life but suppressed in adults. Animal studies suggested that knockdown of Wnt protein led to abnormal kidney development at birth. In the adult kidney, Wnt/beta-- catenin pathway activation led to tissue repair after acute injury, but sustained activation is harmful and involved in renal fibrosis. Recently, Wnt/beta-catenin signaling cascade has emerged as a potential pathway involved in adult renal diseases and is considered an attractive therapeutic target for developing effective therapeutic intervention. Precise information about the involvement of specific types of Wnt/beta-catenin pathway components in adult renal disease using cutting-edge molecular techniques will help develop novel therapies for renal diseases. Future studies will determine Wnt/beta-catenin signaling proteins' effectiveness and safety as a treatment option for renal disorders.Cancer-associated fibroblasts (CAFs) are senescent fibroblasts in tumor nest, which trigger a signaling center to remodel a desmoplastic tumor niche. CAF's functions in cancer are closely similar to myofibroblasts during the wound healing process. They can produce cytokines, enzymes, and protein- or RNA-containing exosomes to alter the function of surrounding cells. Non-- coding RNAs, including microRNAs and long non-coding RNAs, modulate pathologic mechanisms in cancer. Dysregulation of these RNAs influences the formation and function of CAFs. Furthermore, it has been demonstrated that CAFs, by releasing non-coding RNAs-containing exosomes, affect the tumor cells' behavior. CAFs also secrete mediators such as chemokines to alter the expression of non-coding RNAs in the tumor microenvironment. This study aimed to discuss the role of non-coding RNAs in CAF development in cancer. Additionally, we have shed light on the therapeutic approaches to develop the strategies based on the alteration of non-coding RNAs in cancer.Months after WHO declared COVID-19 as a Global Public Health Emergency of International Concern, it does not seem to be flattening the curve as we are still devoid of an effective treatment modality and vaccination is in the first phase in many countries. Amid such uncertainty, being immune is the best strategy to defend against corona attacks. As the whole world is referring back to immune-boosting traditional remedies, interest is rekindled in the Indian system of Medicine, which is gifted with an abundance of herbal medicines as well as remedies. Among them, spices (root, rhizome, seed, fruit, leaf, bud, and flower of various plants used to add taste and flavors to food) are bestowed with immense medicinal potential. A plethora of clinical as well as preclinical studies reported the effectiveness of various spices for various ailments. The potential immune-boosting properties together with their excellent safety profiles are making spices the current choice of phytoresearch as well as the immune-boosting home remedies during these sceptical times.
