It is difficult to diagnose and treat castration-resistant prostate cancer (CRPC) which occurs due to the overexpression of androgen receptor (AR). Because there is a high level of AR in CRPC, we designed and prepared three Pt(IV)-based prodrugs targeting AR. Among them, compound 3, a three-in-one hybrid (an AR binding ligand, a cisplatin unit, and a coumarin moiety), was found to display satisfactory AR binding affinity and antagonist activity against androgen receptor, which could also be effectively internalized and visualized in LNCaP (AR+) cells...

In our search for novel histone deacetylases inhibitors, we have designed and synthesized a series of novel hydroxamic acids and N-hydroxybenzamides incorporating quinazoline heterocycles (4a-i, 6a-i). Bioevaluation showed that these quinazoline-based hydroxamic acids and N-hydroxybenzamides were potently cytotoxic against three human cancer cell lines (SW620, colon; PC-3, prostate; NCI-H23, lung). In term of cytotoxicity, several compounds, e.g. 4g, 4c, 4g-i, 6c, and 6h, displayed from 5- up to 10-fold higher potency than SAHA (suberoylanilidehydroxamic acid, vorinostat)...

Methotrexate (MTX) is a classical chemotherapeutic agent with nephrotoxicity as the most disturbing adverse effect. So far, its underlying molecular mechanisms, particularly PI3K/Akt/eNOS transduction, are inadequately explored. Several antioxidant modalities have been characterized to ameliorate MTX-induced renal injury. In this regard, Camel milk (CM) is a natural product with recognized antioxidant and anti-inflammatory features. Thus, the current study aimed to investigate the potential ameliorating effects of CM in MTX-induced kidney injury in rats...

Prostate cancer is the most common male reproductive system cancer. The prevalence of prostate cancer in Europe and the United States is higher than that in the Asian region. However, the treatment of prostate cancer remains unsatisfactory. Psoralea corylifolia has been used to cure this disease as Chinese medicine in the Asian region. In this study, we analyzed the components of ethanol extraction of unprepared and prepared P. corylifolia by HPLC. Psoralen and isopsoralen content from the prepared P. corylifolia is twofold higher than that from unprepared, so we use the prepared extraction in this study...

PURPOSE: Peritoneal carcinomatosis (PC) from colorectal cancer (CRC) has poor survival. Multi-modal treatment including systemic chemotherapy, cytoreductive surgery (CRS), and hyperthermic intraperitoneal chemotherapy (HIPEC) can be used in selected patients with curative intent. The majority published works consider PC of CRC origin as a homogenous disease. Aim of this study is to stress the different biological behaviors and survival of PC according to colonic or rectal origin. METHODS: Data of CRS and HIPEC procedures for PC of CRC origin performed at MD Anderson Cancer Center-Madrid (Spain) have been collected, dividing patients into two groups according to colonic or rectal PC...

The Musical Instrument Digital Interface (MIDI) was readily adopted for auditory sensorimotor synchronization experiments. These experiments typically use MIDI percussion pads to collect responses, a MIDI-USB converter (or MIDI-PCI interface) to record responses on a PC and manipulate feedback, and an external MIDI sound module to generate auditory feedback. Previous studies have suggested that auditory feedback latencies can be introduced by these devices. The Schultz MIDI Benchmarking Toolbox (SMIDIBT) is an open-source, Arduino-based package designed to measure the point-to-point latencies incurred by several devices used in the generation of response-triggered auditory feedback...

Minimally invasive surgery (MIS) and percutaneous (PC) surgery recently spread as a new technique in operative forefoot correction, and by extension in hindfoot and midfoot. Numerous procedures were described, and a race for MIS and PC has started. However, performing surgery with small incisions should not be an end in itself. Biomechanical and anatomical concerns must be taken into account and shall not be sacrificed for cosmetic reasons. For the most common hindfoot and midfoot pathologies, we discuss what we consider the surgical necessities and then describe the MIS and/or PC procedure we choose, according to these fundamentals...

Pharmaceuticals and personal care products (PPCPs) are contaminants of emerging concern and have been detected worldwide in water bodies in trace concentrations. Most of these emerging contaminants are not regulated in water quality standards except a few in the developed countries. In the case of developing countries, research in this direction is at a nascent stage. For the effective management of Pharmaceutical contaminants (PC) in developing countries, the relevance of PCs as an emerging contaminant has to be analyzed followed by regular monitoring of the environment...

Background: Heart rate variability (HRV) provides information about the activity of the autonomic nervous system. Because of the small amount of data collected, the importance of HRV has not yet been proven in clinical practice. To collect population-level data, smartphone applications leveraging photoplethysmography (PPG) and some medical knowledge could provide the means for it. Objective: To assess the capabilities of our smartphone application, we compared PPG (pulse rate variability (PRV)) with ECG (HRV)...

MicroRNAs (miRNAs) have been implicated in neoplasm growth, metastasis, vasculogenesis, and drug resistance. It has been validated that abnormal miR-195 expression was related with poor survival of prostate cancer (PC); however, its role in the resistance to chemotherapeutic drugs docetaxel (DOC) in PC is still acquainted scarcely. In our study, the lower expression of miR-195 was appeared in DOC-resistant PC cells (DU145/DOC) rather than DOC-sensitive DU145 cells. The up-regulation of miR-195 lowered the IC50 of DOC, facilitated the apoptosis and inhibited the colony formation ability in DU145/DOC cells...

This study was designed to investigate the acute and subacute toxicity of the aqueous extract from colocasia esculenta (CE) leaves infected by Phytophthora colocsiae (PC) in rats. Toxicity of the aqueous extract was evaluated in both male and female wistar rats after a single administration (Acute model) and during 21 days (subacute model). Acute administration of the extract up to a dose 4000 mg/kg did not induce treatment related signs of toxicity or mortality of any rat tested. Therefore, LD50 was estimated to be more than 4000 mg/kg...

NKX3.1/C-MYC cross-regulation has been reported in the normal human prostate, and loss of NKX3.1 and gain of C-MYC seem to be important events in prostate cancer development and progression. The dog can be an interesting model for human prostatic disease, and yet only one previous research study has shown deregulation of NKX3.1 and MYC in the canine prostate. To address the expression of NKX3.1 and C-MYC in different canine prostatic lesions, this study verified the gene and protein expression of NKX3.1 and C-MYC in normal canine prostatic tissues...

We have previously reported a heterogeneous expression pattern of the nuclear membrane protein lamin A/C in low- and high-Gleason score (GS) prostate cancer (PC) tissues, and we have now found that this change is not associated with LMNA mutations. This expression pattern appears to be similar to the process of epithelial to mesenchymal transition (EMT) or to that of mesenchymal to epithelial transition (MET). The role of lamin A/C in EMT or MET in PC remains unclear. Therefore, we first investigated the expression levels of and the associations between lamin A/C and several common EMT markers, such as E-cadherin, N-cadherin, β-catenin, snail, slug and vimentin in PC tissues with different GS values and in different cell lines with varying invasion abilities...

Magnetic dipole interactions are dominate in quasi one-dimensional (1D) molecular magnetic materials, in which TbNcPc units (Tb3+ = terbium(III) ion, Nc = naphthalocyaninato, Pc = phthalocyaninato) adopt a structure similar to TbPc₂ single-molecule magnets (SMMs). The magnetic properties of the [TbNcPc]0/+ (neutral 1 and cationic 2) with 1D structures are significantly different than those of a magnetically diluted sample (3). In particular, the magnetic relaxation time (τ) of 2 in the low temperature region is five orders of magnitude slower than that of 3...
