Authors: Peña Joya Miguel A , Góngora Agustín , Jiménez Claudia 
Published: August 2024

Summary The most important infectious diseases that affect fertility of the bull, and their transmission via semen are reviewed in this article. Additionally, a retrospective analysis of the diseases reported in Colombia was also addressed. In general, there is high sero positivity for IBR and BVD, two diseases that can be transmitted by semen due to viral latency and persistence, and lack official control programs in Colombia. It is necessary to move forward with the support of livestock associations and animal health institutions in order to establish true artificial Insemination centers that allow a permanent surveillance of donor's health status, and the production of pathogen-free semen as a way to control transmission of diseases via semen. Key words: bull, Colombia, fertility, infectious agents. Resumen Se revisa en este artículo las principales enfermedades infecciosas que afectan la fertilidad del toro y su trasmisión por semen. Se analiza a la vez, en forma retrospectiva, el estado sanitario de los reproductores a partir de algunos estudios realizados en Colombia. En general, existe una alta seropositividad para IBR y DVB, dos enfermedades que pueden ser trasmitidas por el semen en razón de la latencia y persistencia viral y para las cuales no existe un programa de control oficial. Se plantea la necesidad de avanzar con el apoyo de las asociaciones ganaderas y las instituciones encargadas de la sanidad Animal en el establecimiento de verdaderas centrales de inseminación artificial que permitan un monitoreo permanente del estado de salud de los donantes y la obtención de semen libre de enfermedades como una forma de controlar la trasmisión por esta vía. Palabras clave: agentes infecciosos, Colombia, fertilidad, toros. Resumo Foi feita uma revisão das principais doenças infecciosas que afetam a fertilidade de touros e sua transmissão pelo sêmen. Também foi analisado retrospectivamente o estado sanitário de reprodutores a parir de alguns estudos realizados na Colômbia. Em geral, há uma alta soro positividade para IBR e BVD, duas doenças que podem ser transmitidas pelo sêmen por causa da latência e persistência viral e para os quais não há um programa de controle oficial. Isso indica a necessidade de avançar com o apoio de associações de animais e instituições responsáveis pela saúde animal no desenvolvimento de verdadeiras estações de inseminação artificial que permitem a monitorização contínua da saúde dos doadores e obtenção de sêmen livre de doença como uma forma de controlar a transmissão por esta via.

Summary Current livestock value of output in Mexico stands at USD 30 billion, of which 58.7% is intermediate consumption and 41.3% value-added. During 2003-2011, livestock value-added grew at 2.46% annually, higher than in both economy and agriculture. In the last 20 years, poultry meat production has kept a dynamic growth, while growth in beef production has been moderate. Pork production has decreased continuously since the mid-1990s, to a great extent due to competition from cheaper and massive imports from the United States. In the last 10 years, Mexico has begun to increase and diversify its meat exports, mainly beef; however, a large trade deficit of nearly USD 3.2 billion annually, persists. Mexico's livestock value-added has the potential to continue growing at least at 2.5% per year, but requires wide-ranging policies to increase and consolidate both its productivity and competitiveness in the long term. Key words: economic growth, livestock production, Mexico, policies, trade. Resumen El valor de la producción ganadera en México es de 30 mil millones de dólares, del cual el 58,7% corresponde al consumo intermedio y el 41,3% al valor agregado. En el período 2003-2011, el crecimiento del valor agregado de la Ganadería fue de 2,46%, superior al de la Economía y superior al del Sector Primario. En los últimos 20 años, la producción de carne de pollo ha mantenido un crecimiento dinámico, mientras que la producción de carne de bovino ha mostrado un crecimiento moderado. La producción de carne de porcino ha disminuido continuamente desde mediados de los noventas, en gran medida debido a la competencia con las masivas importaciones de esa carne proveniente de los Estados Unidos. En los últimos 10 años empiezan a aumentar y a diversificarse las exportaciones de carne, principalmente la de carne de bovino, sin embargo se ha mantenido un gran déficit comercial de productos pecuarios con el exterior, de alrededor de los 3200 millones de dólares anuales. La ganadería de México tiene el potencial para continuar con un crecimiento de al menos 2,5% anual, pero se requieren de políticas de gran alcance para aumentar y consolidar su productividad y competitividad en el largo plazo.

Kehadiran kedua orangtua dalam hidup anak usia dini adalah hal yang sangat penting dalam tumbuh kembangnya. Hadirnya orangtua yang lengkap akan membuat aspek perkembangan anak terstimulasi dengan optimal. Orangtua dapat melakukan pembagian peran yang sama. Meskipun pembagian peran dan keterlibatan sudah terbagi namun nyatanya keterlibatan ayah dinilai sangat minim. Masih banyak ayah yang beranggapan bahwa tugas utama laki-laki adalah bekerja sehingga mengabaikan peran ayah dalam mengoptimalisasi aspek perkembangan anak. Padahal seharusnya keterlibatan dalam mengasuh anak adalah tanggung jawab kedua orangtua yaitu ayah dan ibu. Menurut hasil survey harian online Parapuan edisi 11 Mei 2021 menyatakan bahwa di Indonesia sebagian besar suami istri sudah berbagi peran dalam mengurus anak dengan presentase paling tinggi yakni sebanyak 86,52%. Hal ini menunjukkan peran kedua orangtua sangatlah penting. Selanjutnya penelitian lain menunjukkan bahwa anak perempuan lebih banyak merasakan kedekatan dengan ayah dengan prosentase sekitar 67,05% dibanding dengan anak laki-laki dengan prosentase sekitar 61,59%. Lalu, anak laki-laki lebih merasakan kedekatan dengan ibu dengan prosentase sebesar 88,1% dibanding dengan anak perempuan yang prosentase sekitar 85,25%. Dari tersebut menunjukkan bahwa keseimbangan pengasuhan antara ayah dan ibu sangat penting dilakukan. Penelitian ini menggunakan metode penelitian kuantitatif berupa survey yang dilakukan untuk memperoleh gambaran tentang keterlibatan ayah dalam pengasuhan anak. Teknik analisis data yang digunakan yaitu wawancara, penyebaran kuesioner, dokumentasi dan observasi.

Effective legal protection against the unlawfulness of administrative acts is essentially achieved if the aggrieved party has some form of legal remedy to enforce his/her rights. This remedy may be at the stage of the administrative procedure, however, in some cases it may achieve its real purpose only through judicial means. The right to a fair hearing is closely linked to the right to remedy, which means the possibility of simultaneously appealing to another body or to a higher forum within the same organization regarding decisions on the merits. An essential element of all remedies is the possibility of remedy, i.e. the remedy conceptually and substantively includes the possibility of reviewing of the violation of law. The aim of the person affected is nothing other than to remedy his or her disadvantage. But who can be affected?
Regulation of unlawful waste deposition in the Republic of Slovenia
Authors: Juhart Miha 
Published: August 2024

The Republic of Slovenia transposed its obligations outlined in Directive 2008/98 to the Environmental Protection Act through a legal order. Its first unlawful waste disposal regime was implemented in 2008. The responsibility for unlawful waste disposal is primarily placed on the polluter, while the subsidiary responsibility lies with the real estate owner. The owner of the real estate on which the waste is unlawfully disposed must arrange for proper disposal of the waste at his own expense if ordered by the inspection authority. The subsidiary responsibility of the real estate owner implies strong interference with the right to the property. To date, the Constitutional Court has not yet assessed the compatibility of this measure with the Constitution, as it has taken the view that it will not carry out an abstract assessment but will only make a decision through a constitutional appeal procedure. Despite several concerns, the regulations were maintained in the new Environmental Protection Act of 2022. In addition to the unlawful disposal of waste, this Act also regulates the legal consequences of littering; further, the Act imposes relatively high administrative fines, including on any landowner who fails to exercise his secondary responsibility. Notably, the unlawful disposal of waste is defined as a criminal offence that burdens and destroys the environment. The legal framework, in my opinion, fully meets the requirements of Article 36 of Directive 2008/98/EC.

Published: August 2024

Objectives. To examine linear and nonlinear associations between psychosocial syndemic factors and HIV risk and engagement in HIV prevention care among sexual and gender minority (SGM) youths. Methods. Between February and October 2022, we recruited 17 578 SGM youths aged 13 to 18 years in the United States for an online survey. We examined the relationship of syndemics (i.e., binge drinking, drug use, sexual victimization, and anti–lesbian, gay, bisexual, and transgender discrimination) with sexual behaviors (i.e., sexual initiation, condomless anal or vaginal sex, and number of sexual partners) and HIV prevention care (i.e., HIV testing, preexposure prophylaxis awareness and utilization) using regression. Results. Psychosocial syndemic burden (number of syndemic factors reported) was linearly and cubically associated with engagement in sexual behaviors. Psychosocial syndemic burden was linearly associated with higher HIV testing and preexposure prophylaxis awareness and cubically associated with higher preexposure prophylaxis utilization. Conclusions. Our findings are evidence of synergism across psychosocial syndemic factors regarding HIV risk and engagement in HIV prevention care among SGM youths in the United States. Public Health Implications. Multicomponent interventions may help reduce HIV risk and promote access to HIV prevention services among SGM individuals aged 13 to 18 years.

Interference with GINS2 inhibits ovarian cancer cell cycle entry by degrading CyclinA2 through ubiquitination
Authors: Lin Bei , Zhao Yue , Lin Bei , Rehman Aziz 
Published: August 2024

Abstract

The abnormal regulation of the cell cycle in tumor cells is linked to their proliferation, drug resistance, and recurrence. However, the mechanisms behind cell cycle regulation still need to be revealed for malignant tumor treatment. In this study, we conducted a bioinformatics analysis on the ovarian tissue mRNA microarray datasets from the GEO database. It revealed the involvement of GINS complex subunit 2 (GINS2), one of the main components of CMG helicase, not only in DNA replication, but also in cell cycle regulation. Experimental verification showed that GINS2 was regulated by cell cycle transcription factor E2F1 and could, in turn, improve the expression of Cyclin A2, promoting the transformation of cell cycle G1/S phase and the proportion of S phase. Surprisingly, GINS2 affected Cyclin A2 expression via ubiquitin degradation of MCM7 independent of the P53 and P27-associated extranuclear pathways. These findings emphasize GINS2's significance in the functional regulation of CMG helicase. The study concludes that GINS2 is a key player in the direct feedback up-regulation of the cell cycle through affecting Cyclin A2 expression, providing new insights into cell cycle regulation mechanisms.

Published: August 2024

Abstract

In order to study the effects of different lithologic aggregates on the interaction between aggregate-asphalt micro interface, the researchers conducted microscopic tests to analyze the aggregates' chemical composition, micromorphology, and micro roughness. Metal plates were also used as a control group for comparison. In addition, the researchers used a contact angle measuring instrument to investigate the coating effect of asphalt and aggregate at high and medium temperatures. The mechanical properties of the aggregate-asphalt-aggregate system under various adhesion conditions were comprehensively explored through dynamic shear rheology tests and direct tensile tests of the aggregate-asphalt interlayer. The results showed that the microscopic coating effect of asphalt and aggregate and the micro-roughness of the aggregate had a nuanced relationship. The basalt-asphalt interface was found to have good high-temperature properties, while the limestone-asphalt interface demonstrated optimal medium-temperature properties. Lastly, the granite-asphalt interface was found to have the best low-temperature crack resistance.

Abstract

Background:A comparative study was conducted in the Bio-control laboratory, Department of Entomology, College of Agriculture, Odisha University of Agriculture and Technology, Odisha, India during 2020-21 and 2021-22 to determine the effects of different combination of carbohydrate and protein source artificial diets on larval duration, egg hatchability and sex ratio of green lacewing, Chrysoperla zastrowi sillemi (Esben-Peterson).Six adult diets i.e.,Diet 1 (Water,Honey and Protinex), Diet 2 (Water, Honey and Castor pollen), Diet 3 (Water, Honey, Protinex and Castor pollen), Diet 4 (Water, Molasses and Protinex), Diet 5 (Water, Molasses and Castor pollen) and Diet 6 (Water, Molasses, Protinex and Castor pollen) were evaluated along with check (Diet 7 =Water and Honey).
Results: Maximum developmental period of first, second and third instar larvae i.e., 3.40 days, 3.10 days and 3.16 days were recorded in Diet 1, respectively followed by Diet 3 i.e., 3.37 days, 3.07 days and 3.12 days, respectively.Highest egg hatching percentage of 98.78% was recorded in Diet 1 with 6.90% increase in egg hatching percentage over check (Diet 7)followedby 97.89% and 97.56% in Diet 3 and Diet 2 with 5.94% and 5.59% increase in egg hatching percentage over control, respectively.Most desirable female-biased sex ratio (male: female) was observed in Diet 1 i.e.,1:1.86 followed by Diet 3i.e.,1:1.79 and Diet 2i.e., 1:1.74.
Conclusions: It is clear that feeding adults a fresh food would improve the survivability and predatory efficiency of Chrysoperla zastrowi sillemi larvae. The development and growth of this predator can be enhanced with a semi-defined diet. In comparison to natural foods like nectars, diets high in carbohydrates and protein are more suited to and convenient for adults when raising green lacewings in large numbers.

Abstract

Cancer, particularly lung cancer, remains a leading cause of mortality worldwide, highlighting the need for new remedies. The brown algae species, C. indica, has gained attention for its rich phytochemical composition and pharmacological potential. This study evaluated the genotoxic and cytotoxic effects of C. indica extract on human gingival fibroblast (HGF) and lung cancer (A549) cell lines. Algae materials were extracted using sequential maceration, and fucoxanthin content was determined via High-Performance Liquid Chromatography (HPLC). Cytotoxic and genotoxic effects were assessed using MTT and comet assays, with statistical analyses performed using GraphPad Prism software. The algal sample contained 3.077 μg of fucoxanthin per 1g in n-hexane-acetone extract and 4.32 μg of fucoxanthin per 1g in ethanolic extract. n-Hexane-acetone and cold water extracts at 5000 µg/mL concentration exhibited the highest antioxidant activities in the DPPH assay with IC50 values of 306.15 ± 18.46 μg/mL and 8370 ± 2460 μg/mL, respectively. n-Hexane-acetone extract induced 50.66% apoptosis and hot water extract caused 54.97% apoptosis at 100 µg/mL. C. indica offers unique metabolites with potential pharmaceutical applications, especially as cytotoxic agents against cancer. The n-hexane-acetone extract, rich in flavonoids and phenolics, showed significant antioxidant and anticancer effects, inducing notable apoptosis in A549 cancer cells, suggesting further investigation for anticancer use.
