A temporary portocaval shunt (TPCS) associated with retrohepatic vena cava preservation prevents the edema caused by splanchnic congestion during liver transplantation (LT), especially for non-cirrhotic cases. We herein report a modified TPCS technique using the recanalized umbilical vein and an end-to-side recanalized umbilico-caval anastomosis for use during pediatric living donor liver transplantation (LDLT). This work evaluated a group of pediatric patients who underwent LDLT between 2001 and 2014 with the conventional TPCS (n=16) vs the recanalized umbilico-caval shunt (the crossed fingers method, n=10). The crossed fingers method was performed by suturing an end-to-side anastomosis of the patent or recanalized umbilical vein to the vena cava using a continuous monofilament suture like "crossing the fingers," that is, placing the left portal vein across the portal vein trunk next to it. The preoperative, surgical, and postoperative characteristics were similar in both groups except for the significantly shorter portal vein clamping time for the crossed fingers method. This method can allow the portal circulation to be totally decompressed before and after implanting the graft and while maintaining the hemodynamic stability throughout all stages of pediatric LDLT.

An involvement of a new zinc finger protein PbrZFP719 into pear self-incompatibility reaction.

This study indicated that the CCHC-type zinc finger protein PbrZFP719 involves into self-incompatibility by affecting the levels of reactive oxygen species and cellulose content at the tips of pollen tubes. S-RNase-based self-incompatibility (SI) facilitates cross-pollination and prevents self-pollination, which in turn increases the costs associated with artificial pollination in fruit crops. Self S-RNase exerts its inhibitory effects on pollen tube growth by altering cell structures and components, including reactive oxygen species (ROS) level and cellulose content.

Finger amputations following complex hand injuries (CHI) pose a significant challenge in hand surgery due to severe tissue trauma and neurovascular damage, necessitating precise arterial repair. While restoring arterial perfusion is critical, it remains unclear whether reconstructing both proper palmar digital arteries is required for optimal outcomes. This study evaluates whether restoring one or both arteries in finger replantation after complex injuries impacts perfusion and overall outcomes.

Background: No treatments exist for apathy in people with frontotemporal dementia. Previously, in a randomised double-blind, placebo-controlled, dose-finding study, intranasal oxytocin administration in people with frontotemporal dementia improved apathy ratings on the Neuropsychiatric Inventory over 1 week and, in a randomised, double-blind, placebo-controlled, crossover study, a single dose of 72 IU oxytocin increased blood-oxygen-level-dependent signal in limbic brain regions. We aimed to determine whether longer treatment with oxytocin improves apathy in people with frontotemporal dementia.

This study develops predictive models for Chinese female patients with VL utilizing machine learning techniques. The aim is to create an effective model that can assist in clinical diagnosis and treatment of vaginal relaxation, thereby enhancing women's pelvic floor health. In total, 1184 women with VL have been randomly selected and categorized into groups using the finger measurement method.

Background: Frailty is a syndrome associated with age-related impairments in multiple organ systems, of which the autonomic nervous system plays a fundamental role. Measurement of heart rate variability (HRV) is a non-invasive method to evaluate the autonomic activity and gain insights into cardiovascular health and potentially, frailty. A few small studies have explored the relationship between HRV and frailty, with promising but conflicting results.
