Sudden death syndrome in broiler chickens: a review on the etiology and prevention of the syndrome
Authors: Sosnówka-Czajka Ewa , Skomorucha Iwona 
Published: March 2022

Abstract
Sudden death syndrome (SDS) is a condition in which apparently healthy broiler chickens die suddenly. There are short convulsions and frantic wing-beating prior to death, and the weight of internal organs is the same as in healthy chickens. The exact etiology of SDS is unknown. Heart problems have been implicated as a potential cause of the disease in broiler chickens. Despite considerable research, effective methods of prevention are still being sought. Furthermore, the prophylactic measures often make production less profitable (reduced body weight gain resulting from restricted feeding) and prolong the growth period. It is necessary to continue research on SDS, in particular on stimulation of the cardiovascular system to reduce the susceptibility of broilers to sudden death syndrome under intensive production systems.
Nanowater enhances cryoprotective properties of glycerol-containing extenders used for ram semen freezing: A preliminary study spanning laboratory testing
Authors: Szymanowicz Joanna , Murawski Maciej , Schwarz Tomasz , Bartlewski Pawel M. 
Published: March 2022

Abstract
It has been suggested that nanowater (NW-water declustered in the cold plasma generator and characterized by a low freezing point and high diffusivity) could improve ram semen quality after freezing in glycerol-containing extenders. Eighteen ejaculates from six Olkuska rams were divided into six equal portions each, and then diluted (800×106 spermatozoa/ml) and frozen in the fructose-skimmed milk-egg yolk Kareta extenders containing 3% or 7% of glycerol. The extenders were prepared with deionized water (DW-3% and DW-7%) or NW declustered for 15 min (NW15’) or 30 min (NW30’). Post-thaw sperm motility, proportions of sperm defects and percentages of apoptotic, necrotic, and live spermatozoa were determined. The proportion of spermatozoa with midpiece defects was lower (P<0.05) in NW15’-3% compared with DW-3%. Sperm progressive motility was greater (P<0.05) for spermatozoa cryopreserved in both NW30’ (NW30’-3%/7%) extenders compared with their respective controls (DW30’-3%/7%). The proportion of necrotic spermatozoa 1 h after thawing was lower (P<0.05) in NW30’-7% compared with DW-7%, whereas the proportion of live cells detected immediately and 1 h after thawing was greater (P<0.05) in NW30’-7% than in DW-7%. In summary, NW enhanced cryoprotective effects of glycerol-containing extenders with an increase in sperm viability being greater with 7% than 3% of glycerol. Different declustering times appear to alter NW properties. These observations merit future studies of the utility of NW for semen cryopreservation in rams and other mammalian species. The specific mechanisms whereby NW ameliorates the quality of frozen-thawed ram spermatozoa remain to be elucidated.

Published: March 2022

Abstract
Adding antioxidants to semen extender has become one of the major strategies to reduce the damage caused by freezing to stallion sperm. Isoespintanol (Iso) is a natural antioxidant that is known as a good free radical scavenger. The aim of this research was to evaluate the effect of supplementation of freezing media with Iso on functional integrity of equine semen. Semen from five Colombian Creole horses was frozen with 0, 10, 20, 30, 40 and 50 µM Iso. Post-thawing motility and kinetics, structural membrane integrity (SMI), normal morphology (NM) and functional membrane integrity (FMI) of sperm were evaluated. Seminal quality (SQi) and seminal velocity (SVi) indexes were calculated. Through a flow cytometric analysis, mitochondrial membrane potential (ΔΨM), viability and DNA integrity of frozen-thawed semen were assessed. General linear models were adjusted, and means comparisons were performed using Tukey’s test. The significance level was P<0.05. No differences for post-thaw sperm quality parameters were found, except for total motility, which showed a reduction by adding 40 µM Iso (P<0.05). However, the estimation of indexes, showed that supplementation with 20 or 30 µM Iso before semen freezing, can increase post-thaw SQi and SVi values of some horses. A higher proportion of high-∆ΨM sperm for 20 µM Iso was found. It is concluded that Iso can improve the quality and mitochondrial activity of frozen-thawed equine semen, however its effect can vary according to the horse and in high concentrations it could have detrimental effects.

Abstract
The present study was aimed to evaluate the moderating properties of lavender (Lavandula officinalis) essential oil (LEO) against immunotoxic effects of the organophosphate pesticide, malathion in rainbow trout, Oncorhynchus mykiss. For this purpose, fish were supplemented with LEO at dietary concentrations of 0.5, 1, 2 and 4 ml/kg diet LEO for 56 days. A non-LEO supplemented group was also considered as control. After 57 days feeding trial, biochemicals were assayed in the blood and kidney tissue and then fish exposed to a sub-lethal concentration of malathion [0.24 mg/l equal to 30% of LC50 (0.8 mg/L)]. After 57 days feeding trial, the serum total immunoglobulin, respiratory burst activity, lysozyme activity and complement activity significantly elevated in fish treated with 1 and 2 ml LEO/kg diet compared to non-LEO supplemented individuals (P<0.01). Such changes were not observed in non-LEO supplemented fish (P>0.01). Significant elevations were observed in the expression of the immune genes (iNOS and C3 genes) in fish treated with 0.2–2 mg LEO/kg diet compared to non-supplemented ones (P<0.01). The lysozyme and complement activity significantly decreased in fish fed 4 ml/kg diet (P<0.01). After exposure to malathion, all immune components significantly declined in control and those treated with 0.5, 1 and 4 ml LEO/kg diet (P<0.01). In contrast, the immunity components exhibited no significant changes in fish treated with 2 ml LEO/kg diet after exposure (P>0.01). The expression of iNOS and C3 genes significantly reduced in control and fish fed 0.5, 1 and 4 ml LEO/kg diet in response to malathion (P<0.05). Furthermore, the expression of these genes showed no significant changes in fish fed with 2 ml LEO/kg diet after exposure (P>0.01). The findings of the present study suggested an immunoprotective role for dietary LEO at optimized dietary concentrations of 1 and 2 ml LEO/kg diet against oxidative stress and toxicity induced by malathion. Nevertheless, LEO at high dietary concentration (4 ml/kg diet) had reducing effects on the fish immunity.

Published: March 2022

Abstract
This work aims to analyze the age structure of forests in Krasnodar Krai in order to estimate their carbon sequestration potential. The research was conducted during 2015–2020 in 14 forested districts of Krasnodar Krai in the Russian Federation. A database of 96,000 sample plots was used. Aspen occupied the maximum area (20% of trees), while much smaller areas were occupied by linden, birch, pine, and oak (p≥0.05 with aspen). Spruce occupied three times smaller areas compared to aspen (p≤0.05), while maple, elm, ash, and alder had ten times smaller areas (p≤0.01). Among deciduous species by age, mature and overmature stands predominate, while in conifers a young growth prevails (44% – for pines). All pine forests belong to the 1st quality class (91%), for birch and aspen, it is 75–80% of trees (p≤0.05 with the frequency for pine), for spruce – 52% (p≤0.05), and for oak – 10% (p≤0.01). Different tree species make different contributions to carbon sequestration – from 0.3 tons per 1 ha (Alnus glutinosa) to 1.7 tons per ha (Fraxinus excelsior). Taking into account the areas occupied in the forest by different tree species, their contribution will also be different – from 0.5 thousand tons/1 year (F. excelsior) to 290 thousand tons per 1 year (Populus tremula). The total increase in wood stocks and carbon sequestration is mainly due to six forest tree species. The results obtained can be used to assess the potential for carbon sequestration in temperate forests, taking into account their different age structure and tree species composition.
The Adoption and Implementation of High-Performance Work System in Subsidiaries of Japanese Multinational Companies in Vietnam: a Qualitative Study
Authors: Tran Huy Phuong , Dinh Thi Ngoc Quynh , Nguyen The Kien 
Published: March 2022

Abstract

Background and purpose: Managing human resource in foreign subsidiaries of Multinational Companies (MNCs) has been a challenging task due to the cultural diversity. High Performance Work System (HPWS) has been adopted by headquarters of MNCs in their subsidiaries as a form of control. The current research aims to explore the adoption and implementation of HPWS in subsidiaries of Japanese MNCs in Vietnam.

Design/Methodology/Approach: A qualitative research design was conducted with data collected from semi-structured in-depth interviews with 33 managers working in 11 subsidiaries of Japanese MNC in Vietnam. Content analysis was used to analyze the data.

Results: The results suggested that although HPWS was not fully implemented in these establishments, ability enhancing, motivation enhancing and opportunity enhancing bundle of HPWS were adopted to a varying extent. In addition, HPWS was adopted as a reactive response rather than a strategic choice. Finally, cost-benefit consideration may provide explanation for the non-systematic implementation of HPWS in affiliations of Japanese MNCs in Vietnam.

Conclusion: The research provides some evidences to support the best-fit approach to HPWS adoption and implementation. Although HPWS has the potential to improve organizational performance, it must be internally aligned with the context of the organization.

Abstract

OBJECTIVES. To evaluate measurements of sella turcica on computerized tomography (CT) scans.

MATERIAL AND METHODS. Using CT images of 185 subjects (122 male, 63 female), sella length (SL), posterior clinoid height (PCH), tuberculum sella (TS), sella height anterior (SA), sella middle height (SM), sella height posterior (SP), and sella anterior-posterior dimension (SAP), sella types (oval, circular and flattened) were measured in age groups (< 26, 26–40, 41–60, and > 60 y).

RESULTS. In the 41-60y group, the SL and SAP dimensions of the males (n=39) and SM, TS and PCH of the females (n=17) were longer than in the younger group [for males, 26-40y (n=32) and < 26y (n=38) groups; for females, 26-40y (n=19) and < 26y (n=19) groups]. In both males and females, mainly the circular type sella was observed (64.8% and 74.6%, respectively). The SL and SAP distance of the flat sella (n=46) was significantly longer, and the PCH, TS, SA and SM measurements of the flat sella were significantly shorter than those of the oval (n=13) and circular types (n=126).

CONCLUSION. The development of sella turcica continues through the age of 41 to 60 years. In the male group, growth was detected mainly in the anterior-posterior direction. The reason for this may be related to the decrease in the pars anterior of the pituitary gland and the enlargement of the pars posterior of the pituitary gland. However, in females, growth was detected mainly in the vertical direction. This is thought to be due to pituitary stalk elongation.

What are the potential sources of on-farm contamination of raw milk butter with Escherichia coli?
Authors: Gérard Amaury , Barbosa Naomi , Tanna Sybille Di , Sindic Marianne 
Published: March 2022

Description of the subject. According to Regulation (EC) No 2073/2005, Escherichia coli must be enumerated in raw milk butter before sales. Hygiene of batches is acceptable when a maximum of two samples out of five have levels of E. coli between 10 and 100 cfu·g-1. E. coli is still a threat to the safety of raw milk butter. Objectives. This study aimed to identify sources of E. coli in six farms facing recurrent contaminations in butter. Method. Farms were visited three times between March and May 2021. Surface samples and dairy products samples were collected throughout the process for E. coli enumeration and assessment of potential correlations between equipment contamination and hygienic quality of food products. Results. Two major sources of contamination were identified: the lack of efficacy of cleaning and disinfection practices on milk pipelines, junctions and cream separators, and absence of milk cooling in case of time-lapse of more than 2 h between milking and skimming. The use of lactic acid starters could be a helpful way to control E. coli during cream maturation, in association to adequate good manufacturing practices. Conclusions. Levels of E. coli in the considered raw milk butter batches were really high. A new decision tree is proposed that could help manufacturers and food controllers to improve hygienic quality of raw milk butter.

ABSTRACT
The Palu City Government plans to reactivate the biogas power plant (PLTBg) project in Kawatuna landfill, which was operated in 2013. Both economic and environmental benefits of the project are important for decision makers. The environmental benefit include the potential reduction of greenhouse gases (GHGs) emissions by the project. The economic benefits are important to estimate as the financial attractiveness of the project, which include the electricity generated and revenue from Certified Emission Reduction (CER). This study aims (1) to estimate the potential GHGs emissions produced by the Kawatuna landfill before PLTBg project, (2) to estimate the potential GHGs emissions reduction due to the project, (3) to calculate the potential CER that can be obtained from the project. This study employs Clean Development mechanism (CDM) AMS-III.G method to estimate the potential GHGs reduction and a simple quantitative analysis to calculate the potential CER of the project. The results show that based on the BAU Scenario in 2021, the estimated baseline GHGs emissions is 16.148,74 t CO2e, the potential GHGs reduction after the project would reach 61,40% of the total GHGs emissions generated and the range of potential CER would be from 28.595.318 IDR to 72.329.334 IDR. From 2021 to 2030, total present value of CER would reach 563.358.389 IDR.

Resistencia a los anticuerpos monoclonales anti-EGFR en el tratamiento del carcinoma de cabeza y cuello
Authors: Lazo Roblejo Yaily , Morales González Maraelys 
Published: March 2022

Introducción: Los anticuerpos monoclonales dirigidos al receptor del factor de crecimiento epidérmico (EGFR) han demostrado beneficio clínico en el carcinoma de cabeza y cuello en estadios avanzados, sin embargo, a pesar de los alentadores resultados iniciales, los estudios clínicos evidencian que hay pacientes que presentan tasas de respuesta muy pobres o nulas con su uso.
Método: Se realizó una revisión de la bibliografía científica en las fuentes especializadas Medline, Cochrane Library y Google académico sobre los mecanismos moleculares de resistencia que pueden estar involucrados en la reducción de la eficacia de los anticuerpos monoclonales cetuximab y nimotuzumab.
Resultados: En el caso del cetuximab, se exponen los mecanismos de resistencia intrínseca y adquirida tales como: la presencia de los polimorfismos EGFR-K521 y AURKA Phe31-Ile, la activación de puntos calientes de mutaciones en PIK3CA y KRAS/HRAS, la pérdida de expresión de PTEN, las mutaciones en el dominio extracelular del EGFR, la sobreexpresión de MET e inducción de la transición epitelial-mesenquimal, así como algunos mecanismos que involucran las vías AKT/PI3K, RAS/RAF/MEK/ERK y JAK/STAT. Con respecto al nimotuzumab, la literatura refiere que los mejores resultados clínicos con su uso se han asociado con la sobreexpresión del EGFR.
Conclusiones: Los mayores desafíos en el carcinoma de cabeza y cuello son comprender la resistencia a estas terapias e identificar biomarcadores predictivos de respuesta para la selección adecuada de los pacientes. Aunque son múltiples las propuestas de biomarcadores que se publican, requieren su validación en ensayos clínicos prospectivos para su introducción en la práctica clínica habitual. Se sugiere la necesidad de incrementar los estudios sobre los mecanismos de resistencia al nimotuzumab.
