For prophylaxis of severe signs of the postcolectomy and diarrheal syndromes, as well as the secondary anal incontinence syndrome, occurring after extended radical operation--colectomy, extremely low anterior rectal resection, mucosectomy, performed for severe diffuse nontumoral colon diseases, a pelvic small-intestinal anatomic-functional reservoir construction of a new type, which includes a small-intestinal reservoir with ileoendoanal anastomosis, was elaborated. In accordance to data on roentgenological control of the contrast small-intestinal transit the laws of its abdominal localization and peculiarities of morphological reconstruction in late terms after the operation were established. Application of a new type construction elaborated in 26 patients have permitted to reduce the occurrence rate for postoperative complications and the disease recurrences essentially, as well as to improve functional results of treatment.

One-time programmable (OTP) memory is an essential component in chips, which has extremely high security to protect the stored critical information from being altered. However, traditional OTP memory based on the thermal breakdown of the dielectric has a large programming current, which leads to high power consumption. Here, we report a gate tunneling-induced "cold" breakdown phenomenon in carbon nanotube (CNT) field-effect transistors, and based on this we construct a "cold" fuse (C-fuse) memory where applying a mild gate voltage can break down the CNT channel without damaging the gate dielectric.

The noninvasive prenatal test (NIPT) for genetic screening has been adopted globally as an alternative to first-trimester and quad screening due to its high sensitivity and specificity. NIPT involves detecting and processing foreign fetal DNA in maternal circulation to screen for fetal aneuploidy. An incidental consequence of this process is the detection of foreign tumor cell DNA in maternal circulation in otherwise asymptomatic patients.

Background: Leishmaniases are neglected tropical diseases with great clinical and epidemiological importance. The current chemotherapy available for the treatment of leishmaniasis presents several problems, such as adverse effects, toxicity, long treatment time, and parasite resistance. The discovery of new therapeutic alternatives is extremely essential, and the discovery of cellular targets is a tool that helps in the development of new drugs.

Reverse flotation separation of muscovite from apatite using a dodecylpyridinium chloride (DPDC) ionic liquid as the collector was studied in this work. The microflotation results depicted that DPDC had a strong collecting for muscovite but had a slight collecting for apatite when using phosphoric acid as a depressant for apatite in a weakly acidic pH value pulp, artificial mixture mineral flotation showed that reverse flotation separation of muscovite from apatite can be effectively achieved in the reagent scheme of phosphoric acid/DPDC, and DPDC had a better separation performance in the muscovite/apatite system than DDA. The adsorption measurements indicated that the adsorption amount of DPDC on the apatite surface was less than that of DPDC on the muscovite surface, and the zeta potential results confirmed that a strong interaction occurred between DPDC and the muscovite surface, while an extremely weak interaction occurred between DPDC and the apatite surface in the presence of phosphoric acid at pH ∼ 5.

Purpose: Under-five mortality is a key public health indicator, highly responsive to preventive interventions. While global efforts have made strides in reducing mortality rates in this age group, significant disparities persist, particularly in Sub-Saharan Africa. This study aimed to systematically review the factors influencing under-five mortality in Africa, focusing on sociodemographic factors and health-related determinants.
