Joint variation of price and treatment effect size can help assess the cost-effectiveness of a potential Alzheimer's disease treatment.An anticancer drug, cisplatin (CDDP) conjugated gold nanoparticles (GNPs) via L-Lysine (Lys) linker exhibiting a significant toxicity against cancer cells. The produced nanodrug (GNPs-Lys-CDDP) was charachterized by UV-Vis spectroscopy, dynamic light scattering (DLS), Zeta potentials and electron force microscopy. The cytotoxic efficacy of the GNPs-Lys-CDDP against human breast cancer cells (SKBR3) and normal cells (MCF-10A) was evaluatedby MTT assay. Cell apoptosis and morphology changes were assessed by flowcytometery and acridine orange/ethidium bromide (AO/EtBr) staining, respectively. It was found that the GNPs-Lys-CDDP with a size of 85 nm and negatively charged with a zeta-potential of about -25 mV could be taken up by tumor cells. A marked change in the UV spectrum of GNPs-LysCDDP compare to GNPs showed a strong absorption shift in the 525 nm region. The LD50 of GNPs-Lys-CDDP against SKBR3 (1 µg.ml-1), was found to be 8 times lower than that of naked CDDP against SKBR3 (8 µg.ml-1). The nanocomplex GNPs-Lys-CDDP also significantly increased the apoptosis of SKBR3 with the lowest cytotoxic effects on normal cells. www.selleckchem.com/EGFR(HER).html This work indicates that GNPs effectively could decrease the lethal dose of CDDP to 87%. Hence, GNPs modified by Lys, could be a good nano-carrier for chemotherapeutic drugs.The coronavirus disease 19 (COVID-19) is a highly pathogenic and transmissible viral disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which originated in the city of Wuhan, Hubei Province, Central China and spread quickly around the world. The genome sequence of SARS-CoV-2 is phylogenetically related to batderived severe acute respiratory syndrome-like (SARS-like) coronaviruses, therefore bats could be the possible primary reservoirs. At present, there are no clinically approved vaccines or specific antiviral drugs for COVID-19. However, several broad-spectrum antiviral drugs have been evaluated against COVID-19 in clinical studies and resulted in the improvement of patients. In this regard, other therapies such as antiviral drugs, antibodies, stem cells and plasma therapy are being studied. In the current study, we reviewed the emergence, pathogenicity and the genome structure of COVID-19 infection. The main focus of this study is on the therapeutic approaches that may be effective against SARS-CoV-2.Helicobacter pylori, the most frequent pathogens worldwide that colonize around 50% of the world's population, cause important diseases such as gastric adenocarcinoma, chronic gastritis, and gastric mucosa-associated lymphoid tissue (MALT) lymphoma. In recent years, various studies have reported that H. pylori biofilm may be one of the critical barriers to the eradication of this bacterial infection. Biofilms inhibit the penetration of antibiotics, increase the expression of efflux pumps and mutations, multiple therapeutic failures, and chronic infections. Nanoparticles and natural products can demolish H. pylori biofilm by destroying the outer layers and inhibiting the initial binding of bacteria. Also, the use of combination therapies destroying extracellular polymeric substances decreases coccoid forms of bacteria and degrading polysaccharides in the outer matrix that lead to an increase in the permeability and performance of antibiotics. Different probiotics, antimicrobial peptides, chemical substances, and polysaccharides by inhibiting adhesion and colonization of H. pylori can prevent biofilm formation by this bacterium. Of note, many of the above are applicable to acidic pH and can be used to treat gastritis. Therefore, H. pylori biofilm may be one of the major causes of failure to the eradication of infections caused by this bacterium, and antibiotics are not capable of destroying the biofilm. Thus, it is necessary to use new strategies to prevent recurrent and chronic infections by inhibiting biofilm formation.Male fertility is closely related to the normal function of the hypothalamic-pituitary-testicular axis. The testis is an important male reproductive organ that secretes androgen and produces sperm through spermatogenesis. Spermatogenesis refers to the process by which spermatogonial stem cells (SSCs) produce highly differentiated spermatozoa and is divided into three stages mitosis, meiosis and spermiogenesis. Spermatogenesis requires SSCs to strike a proper balance between self-renewal and differentiation and the commitment of spermatocytes to meiosis, which involves many molecules and signalling pathways. Abnormal gene expression or signal transduction in the hypothalamus and pituitary, but particularly in the testis, may lead to spermatogenic disorders and male infertility. The phosphoinositol-3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signalling pathway is involved in many stages of male reproduction, including the regulation of the hypothalamus-pituitary-gonad (HPG) axis during spermatogenesis, the proliferation and differentiation of spermatogonia and somatic cells, and the regulation of sperm autophagy and testicular endocrine function in the presence of environmental pollutants, particularly endocrine-disrupting chemicals (EDCs). In the PI3K/AKT/mTOR signalling pathway, mTOR is considered the central integrator of several signals, regulating metabolism, cell growth and proliferation. In particular, mTOR plays an important role in the maintenance and differentiation of SSCs, as well as in regulating the redox balance and metabolic activity of Sertoli cells, which play an important role in nutritional support during spermatogenesis.The coronavirus disease 2019 (COVID-19) is currently a new public health crisis threatening the world. This pandemic disease is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus has been reported to be originated in bats and by yet unknown intermediary animals were transmitted to humans in China 2019. The SARSCoV- 2 spreads faster than its two ancestors the SARS-CoV and Middle East respiratory syndrome coronavirus (MERSCoV) but has reduced fatality. At present, the SARS-CoV-2 has caused about a 1.16 million of deaths with more than 43.4 million confirmed cases worldwide, resulting in a serious threat to public health globally with yet uncertain impact. The disease is transmitted by inhalation or direct contact with an infected person. The incubation period ranges from 1 to 14 days. COVID-19 is accompanied by various symptoms, including cough, fatigue. In most people the disease is mild, but in some other people, such as in elderly and people with chronic diseases, it may progress from pneumonia to a multi-organ dysfunction.
