Pulmonary hypertension, pulmonary embolism and COVID-19: A district general hospital experience from the UK.

Background: Preliminary data suggest that the prevalence of pulmonary hypertension (PH) in patients with COVID-19 is around 13%, but its prognostic role remains unclear. Approximately 3% of patients develop chronic thrombo-embolic pulmonary hypertension (CTEPH) following diagnosis of acute pulmonary embolism (PE). It is recommended that patients are screened for CTEPH if they remain symptomatic 3 months following diagnosis of PE.

Recycling of agro-wastes for Ganoderma lucidum mushroom production and Ganoderma post mushroom substrate as soil amendment.

The in vitro growth of Ganoderma mycelia on six agro-wastes namely, broad bean stalks (BBS), cotton stalk (CS), maize straw (MS), rice straw (RS), sugarcane bagasse (SCB) and wheat straw (WS) supplemented with wheat bran (WB) or corn gluten (CG) was evaluated. Among the substrates used, CS appeared best followed by SCB and RS. WB showed best supplementation for mycelial growth.

International note: Are Emirati parents' attitudes toward mathematics linked to their adolescent children's attitudes toward mathematics and mathematics achievement?

Drawing on data from the 2012 Program for International Student Assessment (PISA) and employing multilevel modeling as an analytic strategy, this study examined the relations of adolescent children's perceptions of their parents' attitudes towards mathematics to their own attitudes towards mathematics and mathematics achievement among a sample of 5116 adolescents from 384 schools in the United Arab Emirates. The results of this cross-sectional study revealed that adolescents who perceived that their parents liked mathematics and considered mathematics was important for their children not only to study but also for their career tended to report higher levels of intrinsic and instrumental motivation to learn mathematics, mathematics self-concept and self-efficacy, and mathematics work ethic. Moreover, adolescents who perceived that their parents liked mathematics and considered mathematics was important for their children's career tended to report positive intentions and behaviors toward mathematics.

Isolation and characterization of multifunctional Streptomyces species with antimicrobial, nematicidal and phytohormone activities from marine environments in Egypt.

Different strategies have been employed for selective isolation of Streptomycetes from 20 marine samples varied in their biological nature. The recovery of Streptomycetes isolates (112) was influenced preferentially by different strategies; sediment samples were the best source of potential candidate Streptomycetes. All isolates exhibited antimicrobial activities with variable spectrum; the most promising isolates (31) were phenotypically characterized and identified as Streptomyces sp.

Identification of mosquito larvicidal bacterial strains isolated from north Sinai in Egypt.

In the present study, two of the most toxic bacterial strains of Bacillus sphaericus against mosquito were identified with the most recent genetic techniques. The PCR product profiles indicated the presence of genes encoding Bin A, Bin B and Mtx1 in all analyzed strains; they are consistent with protein profiles. The preliminary bioinformatics analysis of the binary toxin genes sequence revealed that the open reading frames had high similarities when matched with nucleotides sequence in the database of other B.
