CAMELLIA QUYNHII (THEACEAE, SECT. STEREOCARPUS), A NEW YELLOW SPECIES FROM THE CENTRAL HIGHLANDS, VIETNAM

Camellia quynhii is described and illustrated as a new species of section Stereocarpus (Pierre) Sealy from 12th village, Vu Bon Commune, Krong Pak District, Dak Lak Province. C. quynhii resembles C. dormoyana (Pierre) Sealy but differs in several morphological characteristics: sepals 6–7; petals about 12–15; filaments tomentose at the base; style 3(–4), basally united; capsule 3(–4) locular, 2–6 seeds in each locule. Information on its phenology, distribution, ecology, and conservation status is also provided.Camellia quynhii is described and illustrated as a new species of section Stereocarpus (Pierre) Sealy from 12th village, Vu Bon Commune, Krong Pak District, Dak Lak Province.

Natural and recombinant equine chorionic gonadotropins past and future in animal reproductive technology

Equine Chorionic Gonadotropin (eCG) previously named Pregnant Mare Serum Gonadotropin (PMSG) has been widely used since the 40s in animal reproduction control. It is extracted from the blood of pregnant mares between days 40 and 120 of gestation. Animal welfare organizations have voiced concerns against mares bleeding conditions. There is currently no effective substitute for the natural PMSG. In this review, we summarize the basic knowledge of the structure and biology of eCG, and the research on recombinant eCG production in the past five years

Mapping local patterns of childhood overweight and wasting in low- and middle-income countries between 2000 and 2017

A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall across LMICs between 2000 and 2017, from 8.4% (62.3 (55.1–70.8) million) to 6.4% (58.3 (47.6–70.7) million), but is predicted to remain above the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025. Prevalence of overweight increased from 5.2% (30 (22.8–38.5) million) in 2000 to 6.0% (55.5 (44.8–67.9) million) children aged under 5 years in 2017. Areas most affected by double burden of malnutrition were located in Indonesia, Thailand, southeastern China, Botswana, Cameroon and central Nigeria. Our estimates provide a new perspective to researchers, policy makers and public health agencies in their efforts to address this global childhood syndemic

Three-dimensional laparoscopy in urology: Initial experience after 100 cases

Summary: Objective: To evaluate the efficacy of three-dimensional (3D) laparoscopy in urological procedures in a cohort study compared to two-dimensional (2D) laparoscopy. Methods: From October 2016 to August 2017, 100 patients underwent various urological procedures with 3D laparoscopy performed by a single experienced surgeon at the University Medical Centre of Ho Chi Minh City. The surgeon's subjective assessment of image quality, depth perception, ease of intra-corporeal suturing and knotting was recorded. The State-Trait Anxiety Inventory for Adults (STAI-6) short version was used to quantify aspects of stress experienced during each operative procedure. A subgroup of 73 complicated 3D laparoscopic procedures (nephron sparing nephrectomy, nephrectomy, adrenalectomy, pyeloplasty and ureterolithotomy) was compared to the same clinical parameter group of 74 two-dimensional laparoscopic procedures, performed by the same surgeon in the year before to define the differences in operative time, blood loss and time taken for critical surgical steps during the procedures. Results: Mean time of operation was 112.8 min ± 14.5 (range 45–210 min). Mean estimated blood loss was 54.7 mL ± 8.2 (range 20–100 mL). The surgeon's subjective assessment of image quality, depth perception, operative strain, ease of intra-corporeal suturing, and knotting, and hand–eye coordination was considered as good in 100% of cases. Mean score of STAI-6 was 11.6 ± 2.17 (range 10–22). Subgroup data analysis was all statistically better for 3D compared to 2D. Conclusion: The use of 3D systems in laparoscopic urologic procedures resulted in better image quality and better surgeon performance with lower stress.
