We describe the operative management of extended lateral column fractures according to the revised three-column classification approach in a step-by-step fashion. We show that direct reduction and stable fixation of extended lateral column tibial plateau fractures via a limited arthrotomy and tibia condyle osteotomy, with the use of free subchondral 2.7 mm locking screws is a reliable technique. Subsequently, diverging VA-LCP locking screws further improve the structural properties. It is a straightforward technique and the single lateral approach (Lazy-S) facilitates direct reduction of the articular surface and stable fixation of the fracture fragments under direct vision with good radiological and fair functional outcome...

Tetramethyl thiuram disulfide (thiram) is one of the important pesticides, which is extensively used in agriculture, but if it is combined with the cell membrane, then it causes membrane damage, bone morphogenic inactivation, and inhibited angiogenesis. Thiram has been considered a common cause of tibial dyschondrolplasia (TD) in various avian species, because it becomes the part of feed due to environmental contamination and its overuse in agriculture as pesticides or fungicide. However, there is no systematic study on the changes of the correlation indexes with toxic effect of the thiram in chickens...

The prevalence of cardiovascular diseases is increasing in low and middle-income countries; Nepal's population shows a high prevalence of behavioral risk factors. Our cross-sectional study in the Jhaukhel-Duwakot Health Demographic Surveillance Site (JD-HDSS), located near the capital Kathmandu, explored knowledge, attitude, and practice (KAP) of mothers with young children regarding diet and physical activity and mothers' perception of their children's attitude and behavior toward the same issues. The purpose of our study was to assess needs of the mothers concerning cardiovascular health in general and more specifically regarding diet and physical activity, and to establish a baseline for future intervention in the community by comparing two villages of JD-HDSS...

During the early twentieth century, public health campaigns taught Americans from all strata of society to recognize that a great threat to the health and prosperity of the South was not an enemy abroad, but rather a bloodsucking parasite living underfoot in Southern soil: hookworm. According to the information widely disseminated by these campaigns, hookworm infection was responsible for the physical "backwardness" of Southern men, women, and children. By linking physical and cognitive symptoms to a parasitic source, the public health campaign introduced a new literary tool for constructing characters who are not "quite right" that continues to be employed in contemporary fiction...

Why do people believe blatantly inaccurate news headlines ("fake news")? Do we use our reasoning abilities to convince ourselves that statements that align with our ideology are true, or does reasoning allow us to effectively differentiate fake from real regardless of political ideology? Here we test these competing accounts in two studies (total N = 3446 Mechanical Turk workers) by using the Cognitive Reflection Test (CRT) as a measure of the propensity to engage in analytical reasoning. We find that CRT performance is negatively correlated with the perceived accuracy of fake news, and positively correlated with the ability to discern fake news from real news - even for headlines that align with individuals' political ideology...

In this paper, we propose DeCoST (Drug Repurposing from Control System Theory) framework to apply control system paradigm for drug repurposing purpose. Drug repurposing has become one of the most active areas in pharmacology since the last decade. Compared to traditional drug development, drug repurposing may provide more systematic and significantly less expensive approaches in discovering new treatments for complex diseases. Although drug repurposing techniques rapidly evolve from "one: disease-gene-drug" to "multi: gene, dru" and from "lazy guilt-by-association" to "systematic model-based pattern matching," mathematical system and control paradigm has not been widely applied to model the system biology connectivity among drugs, genes, and diseases...

This study compares the accuracy of (Q)SAR/read-across predictions with the experimental variability of chronic lowest-observed-adverse-effect levels (LOAELs) from in vivo experiments. We could demonstrate that predictions of the lazy structure-activity relationships (lazar) algorithm within the applicability domain of the training data have the same variability as the experimental training data. Predictions with a lower similarity threshold (i.e., a larger distance from the applicability domain) are also significantly better than random guessing, but the errors to be expected are higher and a manual inspection of prediction results is highly recommended...

Background Research has emphasised the essential role of psychosocial risk factors in chronic pain. In practice, pain is usually verified by identifying its physical cause. In patients without any distinct pathology, pain is easily defined as imaginary pain. The aim of this qualitative study was to explore the invisibility of chronic pain, from the patients' perspective. Methods Thirty-four participants with chronic pain were interviewed. The mean age of the participants was 48 years, and 19 of them were women...

Objective: Amblyopia is a neurodevelopmental disorder characterized by visual acuity and contrast sensitivity loss, refractory to pharmacological and optical treatments in adulthood. In animals, the corpus callosum (CC) contributes to suppression of visual responses of the amblyopic eye. To investigate the role of interhemispheric pathways in amblyopic patients, we studied the response of the visual cortex to transcranial Direct Current Stimulation (tDCS) applied over the primary visual area (V1) contralateral to the "lazy eye...

BACKGROUND: The management of metastatic Renal Cell Carcinoma (RCC) has changed dramatically in the last 20 years, and the role of surgery in the immunotherapy's era is under debate. Metastatic lesions interesting pancreas are infrequent, but those harbouring from RCC have an high incidence. If metachronous resections are not rare, synchronous resection of primary RCC and its pancreatic metastasis is uncommonly reported, and accounts for a bad prognosis. CASE PRESENTATION: We report the case of a 68 years old woman, who presented hematuria at hospital incoming, with radiological appearance of a 13 cm left renal mass, with a 2...

In this paper, we propose an active perception method for recognizing object categories based on the multimodal hierarchical Dirichlet process (MHDP). The MHDP enables a robot to form object categories using multimodal information, e.g., visual, auditory, and haptic information, which can be observed by performing actions on an object. However, performing many actions on a target object requires a long time. In a real-time scenario, i.e., when the time is limited, the robot has to determine the set of actions that is most effective for recognizing a target object...

We present the unique case of a 15-month-old male born with biliary atresia and situs inversus totalis and disrupted inferior vena cava who underwent a successful liver transplantation. The patient had previously undergone a failed Kasai procedure and presented with persistent hyperbilirubinemia. The patient was transplanted with a left lateral segment donor having standard arterial anatomy. Technical considerations included identifying completely replaced arterial anatomy in the recipient from the superior mesenteric artery and creating a branch patch between the gastroduodenal artery and HA, anastomosing the donor left hepatic vein to confluences of the donor left, middle, and right hepatic veins, using a "lazy-S" configuration of portal vein anastomosis, and suspending the allograft to the abdominal wall...

β-glucan content spatial distribution characteristics of cultivated barley in Qinghai-Tibet Plateau were investigated based on the data measured from 83 sampling sites. The results showed that β-glucan content exhibited a macrocosm pattern of spatial distribution along the horizontal direction in Qinghai-Tibet Plateau, with staggered patches of different values. Two regions of higher β-glucan content were observed with centers of Guide and Tongde in Qinghai Province and Xiahe and Hezuo in Gansu Province (northeast), and Jiangzi, Bailang, Xietongmen, Shigatse, Lazi, Kangma, Gongga and Qushui in Tibet (southwest)...

OBJECTIVE: Amblyopia or lazy eye is a common visual problem affecting children that cannot correct with lenses. Nitric oxide synthase (NOS) is a critical enzyme that regulates the activity of nitric oxide (NO), a key signaling molecule with multiple roles in many tissues. Among its many activities, NOS has been proposed to be required for normal eye development and altered NOS expression can lead to perturbations in eye development and vision. MATERIALS AND METHODS: To examine the potential role of neuronal NOS (nNOS) in vision loss, we generated a model of monocular deprivation amblyopia in rats...

Compared with playfulness in infants and children, playfulness in adults is relatively under-studied. Although there is no empirical research comparing differences in adult playfulness across cultures, one might expect variations between Western and Eastern societies such as China. While playfulness is typically seen as a positive trait in Western culture, there are hints in Chinese culture that being playful has negative connotations (e.g., associations with laziness and seeing play as the opposite of work)...
