Tree mortality is a key factor influencing forest functions and dynamics, but our understanding of the mechanisms leading to mortality and the associated changes in tree growth rates are still limited. We compiled a new pan-continental tree-ring width database from sites where both dead and living trees were sampled (2,970 dead and 4,224 living trees from 190 sites, including 36 species), and compared early and recent growth rates between trees that died and those that survived a given mortality event. We observed a decrease in radial growth before death in ca...

BACKGROUND: When primary root canal therapy fails, periapical lesions can be retreated with or without surgery. Root canal retreatment is a non-surgical procedure that involves removal of root canal filling materials from the tooth, followed by cleaning, shaping and obturating of the canals. Root-end resection is a surgical procedure that involves exposure of the periapical lesion through an osteotomy, surgical removal of the lesion, removal of part of the root-end tip, disinfection and, commonly, retrograde sealing or filling of the apical portion of the remaining root canal...

OBJECTIVES: Conventional imaging methods are excellent for the morphological characterization of the consequences of osteonecrosis; however, only specialized techniques have been considered useful for obtaining functional information. To explore the affinity of radiotracers for severely devascularized bone, a new mouse model of isolated femur implanted in a subcutaneous abdominal pocket was devised. To maintain animal mobility and longevity, the femur was harvested from syngeneic donors...

OBJECTIVE: To evaluate the optimal duration of antimicrobial prophylaxis in patients undergoing "complicated"' major hepatectomy with extrahepatic bile duct resection. BACKGROUND: To date, 4 randomized controlled trials (RCTs) have assessed the duration of antimicrobial prophylaxis after hepatectomy. However, all of these previous studies involved only "simple" hepatectomy without extrahepatic bile duct resection. METHODS: Patients with suspected hilar obstruction scheduled to undergo complicated hepatectomy after biliary drainage were randomized to 2-day (antibiotic treatment on days 1 and 2) or 4-day (on days 1 to 4) groups...

TP53 truncating mutations are common in human tumors and are thought to give rise to p53-null alleles. Here, we show that TP53 exon-6 truncating mutations occur at higher than expected frequencies and produce proteins that lack canonical p53 tumor suppressor activities but promote cancer cell proliferation, survival, and metastasis. Functionally and molecularly, these p53 mutants resemble the naturally occurring alternative p53 splice variant, p53-psi. Accordingly, these mutants can localize to mitochondria where they promote tumor phenotypes by binding and activating the mitochondria inner pore permeability regulator, Cyclophilin D (CypD)...

Complex words in Hebrew are composed of two non-concatenated morphemes: a consonantal root embedded in a nominal or verbal word-pattern morpho-phonological unit made up of vowels or vowels and consonants. The root carries the core meaning of the word, whereas the word-pattern creates variations on this meaning, determines the word's grammatical characteristics, and carries segmental and suprasegmental information about the word's structure. Research on written-word recognition has revealed a robust effect of the roots and the verbal-patterns, but not of the nominal-patterns, on word recognition...

The critical contribution of CD4+CD25+Foxp3+ T-regulatory cells (Treg) to immune suppression in the tumor microenvironment is well-established. Whereas the mechanisms that drive the generation and accumulation of Treg in tumors have been an active area of study, the information on their origin and population dynamics remains limited. In this review, we discuss the ontogeny of tumor-associated Treg in light of the recently identified lineage markers.

This study aimed to obtain qualitative information about physical activity (PA), sedentary behaviors (SB) and their determinants and about recently retired adults' needs regarding PA interventions. Four focus group interviews were organized. The most commonly reported PA types were walking, cycling, swimming and fitness. The most commonly reported SB were reading, TV viewing, and computer use. Car use was limited. Most adults agreed their habits had changed during retirement. The most striking PA determinant was the feeling of being a 'forgotten group', having too few tailored PA initiatives available...

BACKGROUND: Young adults underutilize current evidence-based smoking cessation strategies; yet social media are widely used and accepted among this population. A better understanding of whether and how young adults try to quit smoking in the context of a social media smoking cessation intervention could inform future intervention improvements. OBJECTIVES: We examined frequency, strategies used, and predictors of self-initiated 24-hour quit attempts among young adults participating in a Facebook intervention...

: Abstracts Background: Implantation failure of in vitro fertilization (IVF) cycles is recognized as one of key problems in contemporary reproductive medicine. Implantation itself is a multifactorial process and one can hardly expect to find a single criterion for the endometrium receptivity. Endometrium biopsy still remains the most applicable technique to diagnose abnormalities causing decrease or complete loss of endometrial receptivity. MATERIALS AND METHODS: We have studied 95 endometrial biopsy samples from 45 patient with I/II stage endometriosis and 40 controls from October 2014 to December 2015...

Drug induced steatohepatitis (DISH), a form of drug induced liver injury (DILI) is characterized by intracellular accumulation of lipids in hepatocytes and subsequent inflammatory events, in some ways similar to the pathology seen with other metabolic, viral and genetic causes of non alcoholic fatty liver disease and steatohepatitis (NAFLD and NASH). Areas covered: This paper provides a comprehensive review of the main underlying mechanisms by which various drugs cause DISH, and outlines existing preclinical tools to predict it and study underlying pathways involved...
