The Impact of Maternal Health Conditions On the Risk of HIE in Newborns
Authors: Sana  , Atiq Ur Rahman  , Sher Alam Khan  , Rabia Tabassum  , Ismail  , Irum Sajid
Published: January 2025

The aim to determine how maternal disorders may impact hypoxic-ischemic encephalopathy (HIE) in the newborn, a severe neonatal condition that is defined by inadequate oxygen supply and brain damage. The findings of this present study were based on data collected from 1,200 pregnancies to determine how factors like hypertension, diabetes mellitus and infections that occur intrauterine affect the risk and severity of HIE. The study was conducted at Pediatrics Department, Ayub Teaching Hospital, and Abbottabad. The study shows that hypertensive disorders were the significant risk factors for HIE as compared to the other diseases (RR = 2.4, p < 0.01), intrauterine infections (RR = 2.1,p< 0.01) and diabetes mellitus (RR = 1.8, p < 0.05). On the other hand, emergency caesarean sections were associated with a threefold increased risk of HIE, which is commensurate with the severity of high-risk deliveries. Neonates who had exposure to multiple maternal conditions confirmed even higher risk of severe HIE, 72 % of such babies (p < 0.01). That can be explained by the fact that the outcomes obtained reflect prior similar research and contribute new knowledge on the impact of the aggregation of those conditions. The study raises the issue of the need for a coordinated system of prenatal care and early identification of the problem combined with such recommendations to reduce the risk of developing HIE and enhance the baby’s condition. The main recommendation put forward would be proper maternal health management especially learnt with complications in pregnancy to help reduce this major cause of neonatal morbidity and mortality.
Social construction of suicide in the Philippines based on the perspectives of undergraduate students from two universities in Metro Manila
Authors: Quintos Mark Anthony
Published: January 2025

A total of 308 undergraduate students from a sectarian, predominantly middle and upper-middle socio-economic class university (n=139) and a stateowned, non-sectarian, predominantly lower socio-economic class university (n=169) were engaged in a survey research that attempted to understand their perceptions on suicide as a phenomenon. Results indicate that the students from the two universities are very similar in their social constructions of the reality of suicide among the Filipino youth: they believe that suicide is primarily due to depression and other mental illnesses, that majority of young Filipinos have thought of suicide at least once, and that almost 1 out of every 3 has attempted the act. While they generally maintain that all members of the youth are at-risk of suicide, many also believe that the risk is particularly high for youth exposed to violence and members of the LGBT. They also tend to believe that suicide is a cry for help and that they are willing, capable, and even duty-bound to help in cases of suicide. The students believe that suicide is a topic often considered taboo in the Philippines but one that needs to be a part of more conversations. Finally, the students are generally undecided on the acceptability of suicide but also disagree with the notion that suicide can never be justified. The findings suggest that the Philippines, particularly its youth, may be ready for conversations and mobilizations in favor of suicide prevention but are still unprepared for the premise of suicide and assisted suicide as justifiable actions.
Balanseng Paggugrupo ng Trabaho: Ang Bisyon ng Parecon ni Michael Albert
Authors:   University of the Philippines Diliman, Eliserio U
Published: January 2025

This paper is a presentation of North American writer and activist Michael Albert’s vision of participatory economics, or parecon. On a first reading Albert’s ideas seems to be unrelated to the issues faced by Filipino workers. But, a closer reading reveals that Albert’s concept of “balanced job complexes” may be connected with the crises faced by our nation. The paper uses Cristina Guevarra’s “Visiting Ericson” and Chuckberry Pascual’s “Cars at the Airport,” to further buttress the assertion that Albert’s ideas are appropriate responses to our current politico-economic order. At the conclusion, two more short stories by Filipino writers, belonging to the genre of future fiction, are elaborated on as prognoses of this same politico economic order. The paper argues that because capitalism cannot just be put up with or reformed, we must begin the theoretical labor of imaging its replacement.
Customer Aggression and Organizational Turnover Among Service Employees in Metro Manila, Philippines
Authors:   Polytechnic University of the Philippines, Bungato Jr. Guillermo , Nartea Mecmack ,   Polytechnic University of the Philippines, Samonte Giscellve Iveth ,   Polytechnic University of the Philippines
Published: January 2025

The “Customer is always right” has been the motto of many service organizations for the longest time. It mirrors companies’ commitment to do their utmost best in creating a good customer environment to ensure that customers enjoy quality service. But there are instances that customers can get aggressive in social interactions with service employees. These instances do not only affect the marketing and sales aspect of the organization but can ultimately affect the service employees’ output quality and even prompt them to quit. This paper examined how customer aggression affects turnover intentions of service employees. This looked specifically on the effects of customer aggression on the emotional exhaustion, job satisfaction, and turnover intentions of service employees. Survey data was collected using stratified sampling from 328 service employees of KFC branches around Metro Manila. These data were analyzed using the GLM module in Jamovi. Results showed that customer aggression indeed influences emotional exhaustion and in turn decreases job satisfaction and increases turnover intentions. The mitigating effects of distributive justice on the customer aggression-emotional exhaustion relationship was confirmed. However, the mitigating effect of organizational pride on the job satisfaction turnover intentions relationship has been found to be significantly weak. These findings revealed the importance of having policies that communicate equity and justice, as well as the existence of rewards and recognition programs that can boost employee morale and loyalty.
A Critical Discourse Analysis of Rodrigo Duterte’s Language on Endo and Labor Unionism
Authors:   University of the Philippines-Los Baños, Briones Jervy
Published: January 2025

Rodrigo Duterte, back in his presidential campaign in 2016, promised to end endo or contractualization. It is a labor practice in the Philippines where companies temporarily employ workers not exceeding six months otherwise regularization comes that obligates employers to pay workers’ benefits. With less than a year remaining in his term as president, endo continues affecting millions of Filipino workers as ending it is no longer a priority of his government. Since taking power, Duterte gave numerous speeches and interviews on some labor issues, such as endo and unionism. Interestingly, his perspective had shifted significantly from being a working class hero to a status quo defender characterized by his red-tagging of labor unions that he sees as communist ‘fronts’ and his refusal to end endo to seek a so-called balance between labor and capital. In this study, I considered the spoken and written discourse of Duterte on contractualization and unionism which can be found online in the websites of different news agencies and the Presidential Communications Operations Office (PCOO). The text and talk then were analyzed through the lenses of Critical Discourse Analysis (CDA), specifically the socio-cognitive approach by Teun van Dijk. The results show that Duterte’s discourse on labor issues exemplifies power and ideology and reinforces social representations against labor unionism.

Pangangapital sa Wika sa Espasyo ng Kolonyal na Moda ng Produksyon sa Pilipinas
Authors:   Polytechnic University of the Philippines, Adaya Jomar
Published: January 2025

This paper focuses on the analysis of the significant role of language in the spaces of mode of production in the country through its contextualization in colonial history from the feudal system to capitalism. Likewise using notes on the growth and spread of neoliberalism as a mechanism of economic control, primarily of powerful countries, issues on policies on language dispensed by the state to its system of education are scrutinized. In this age of globalization where effects of neoliberalism especially on systems of education continue to intensify, this paper contemplates on language as a form of capital to respond to the labor market controlled by global capitalism.

The state as an agent responsible to secure social order is oftentimes given high regard by its citizens based on the premise that it can also guarantee protection of rights through the formulation of laws that set legal boundaries in safeguarding the interests of the people. The state is the actual reality of an ethical idea according to some philosophers, like Hegel, because it is created with a noble purpose of upholding the common good of its subjects, the essence of which is to secure happiness and safety for all. Conflicts may, however, arise in occasions where individual rights run counter with the policies of the land. This is the focus of this study; on the one hand, an intriguing exposition on the exercise of religious freedom of a minority group, and on the other, its conflict with the legal policies promoting a conceived general welfare for the country.
Panimulang Dalumat sa mga Tula ng mga Magkokopra sa Bondoc Peninsula Tungo sa Pagsiyasat sa Panlipunang Kaakuhan
Authors:   Polytechnic University of the Philippines, Peña Romeo
Published: January 2025

Ang papel na ito ay nakasentro sa panimulang pagsusuri sa panitikan na may kaugnayan sa pagkokopra o paglulukad (paglulukad ang taal na tawag sa Lalawigan ng Quezon sa pagkokopra) na ang karamihan ay naisulat ng mga magkokopra o maglulukad sa Bondoc Peninsula (isang distrito sa Lalawigan ng Quezon). Nakaugat ang pagsusuri sa danas at gunita sa pagkokopra na nakapaloob bilang konteksto ng panitikan na karaniwang tumatalakay kung paano nakikibaka at nakikipaglaban ang mga maglulukad sa Bondoc Peninsula sa karapatan sa lupaing kanilang kinokopra at ang karapatang magkaroon ng maaayos na buhay na hindi napagsasamantalahan ng mga panginoong maylupa na nagmamay-ari pa rin ng ekta-ektaryang lupain sa Bondoc Peninsula. Nagiging mabisang kasangkapan ng mga maglulukad ang panitikan, katunayan nito, naglalabas sila ng mga pahayagan na sila mismo ang nag-iimprenta na naglalaman ng mga akdang pampanitikan tulad ng mga tula tungkol sa karanasan nila sa pagkokopra kasama na ang paggunita nila sa kahirapang dinaranas nila sa hanapbuhay na ito, na halos dugo’t pawis ang iniaalay upang kumita lamang ng panustos sa kanilang pamilya. Dito sinubukan ko ang panimulang pagmamapa sa kultura at kasaysayan ng pagkokopra sa Bondoc Peninsula. Gamit ang dalawang halimbawang tula na likha mismo ng mga magkokopra, sinimulan kong dalumatin ang nagiging panlipunang kaakuhan o identidad ng mga maglulukad mula sa danas at gunita nila sa pagkokopra sa Bondoc Peninsula. Ginamit kong batis ang mga akdang tumatalakay sa kalagayan ng Bondoc Peninsula, tiningnan ko rin ang konsepto ni Alejandro Abadilla kung paano nalilikha ang kaakuhan sa panitikan. Samakatuwid, perspektibong pangidentidad at panlipunan ang tinahak na landas ng pananaliksik na ito tungo sa pagkokonsepto ng tinatawag kong “siyasat sa panlipunang kaakuhan”.

Authors:   Pamantasan ng Lungsod ng Muntinlupa, Espada Dennis
Published: January 2025

This article intends to provide some notes on the emergence and development of traditional media in the Philippines such as printed publications, radio, film, television and advertising, including the new media such as online publications and others. It explores the following periods: Spanish colonialism and earlier, reform movement and the Katipunan, Manifest Destiny of the United States, martial law, and current situation. It seeks to create, through review, a preliminary discussion on the history of media ownership, and the economic and political interests underlying it. Aside from mentioning the leading media conglomerates in the world, the article analyzes the effects of liberalization within the framework of neoliberal globalization, and the proposed charter change to accomplish foreign ownership of media. It illustrates the role of printers in the history of the labor movement and the people’s tireless assertion of democracy and press freedom, which includes revealing the killing of media workers one by one through contractualization and the instantaneous killing of journalists through assassination. It was deemed necessary to identify some failures of the media in fulfilling its duties as well as weaknesses in its standards, while emphasizing the call for Filipinization.

This study aims to explore the importance of the learning environment to students' learning performance. Every school, especially teachers, must try to provide the best environment for students so that they have high intentions and enthusiasm for learning. The type of approach used in this study is qualitative which is carried out by survey methods, interviews with teachers, and questionnaires from students in a structured manner. The subject of the study was taken from one of the inclusion elementary schools in the Surabaya area, namely SD Negeri Klampis Ngasem 1/246. After conducting surveys and interviews, it can be concluded that to create a positive environment learning is not imposed on teaching staff alone, but there are other supporting factors such as classroom atmosphere, learning facilities, the environment of the students themselves, the role of parent involvement, and an inclusive school culture that plays a significant role in supporting the creation of a positive environment. Teachers must play an important role in creating a positive learning environment supported by an adequate atmosphere and facilities so that students feel comfortable and safe. If the above factors support each other, a positive learning environment will be created so that students can achieve their full potential.

En el marco del así llamado estallido social chileno el artículo revisa un conjunto de expresiones poéticas que en los últimos años han poetizado la revuelta de octubre a partir de una subjetividad “quiltra”, comprometida con la imaginación de una forma otra de vivir. El corpus que considera esta revisión se centra en una selección de poemas, extraídos de los textos: (re)constitución poética, Rebeldía quiltra, El dado, Un oasis en el desierto y Ad Mapu Constituyente; todos los cuales se leerán desde la perspectiva crítica de una literatura “desapropiada” que busca intervenir (en) lo común desde la palabra “comunalitaria” de un nosotros autoconvocado y rebelde.
Madres, hijas, abuelas: las tensiones entre la supervivencia y la trascendencia en Roza tumba quema, de Claudia Hernández
Authors: Benítez Collado Nerea
Published: January 2025

Se analiza el modo en que la novela de Claudia Hernández, Roza tumba quema (2018), propone una reflexión crítica sobre la guerra y posguerra salvadoreña en la que el sacrificio propio de la militancia del Frente Farabundo Martí para la Liberación Nacional (FMLN) aparece imbricado con el de la maternidad, dos exigencias marcadas genéricamente que se manifiestan como tensión constante en la madre protagonista, así como en los vínculos madre-hija, hilos conductores de la novela. Siguiendo estos hilos se mostrará el papel crucial que las redes tejidas por las mujeres suponen para la supervivencia de la comunidad, especialmente en contextos de violencia y urgencia revolucionaria.
Tránsitos entre el miedo y la ira: feminismo y performance en el estallido social chileno
Authors: Ramírez Rosemary Bruna
Published: January 2025

Este artículo aborda los feminismos y las performances feministas en el contexto del estallido social chileno de 2019, con un enfoque en las emociones del miedo y la ira como motores de acción política. Parte de una revisión del estado de la cuestión, analizando cómo los movimientos feministas en Chile han desarrollado estrategias de resistencia y transformación desde la dictadura cívico-militar hasta el presente, articulando demandas que van más allá de las cuestiones de género para incluir críticas al modelo neoliberal. El objetivo central es explorar cómo el feminismo chileno resignifica emociones tradicionalmente vistas como paralizantes o destructivas, transformándolas en herramientas políticas que cohesionan a las comunidades y fortalecen las movilizaciones. Se sostiene que estas emociones no solo operan en el plano individual, sino que se entrelazan para articular colectividades resilientes y generar demandas de justicia social. A través del análisis de performances emblemáticas como "Un violador en tu camino" y otras performances feministas, se evalúa cómo el cuerpo y los afectos aparecen en el espacio público como elementos de transformación política.

Patrum imagines: metamorfosi della paternità in Ovidio (parte 2)
Authors: Zanfardino Antonio
Published: January 2025

Partendo da un’indagine dell’importanza del motivo parentale nell’ideologia augustea, il contributo intende analizzare la deformazione mitica dell’immagine paterna operata da Ovidio nelle Metamorfosi, individuando in essa una delle tante espressioni di instabilità presenti nell’anomalo poema epico. In particolare, la rappresentazione deviante che l’autore fornisce di tre padri mitici –Febo, Dedalo e Teseo, questi ultimi due oggetto della presente riflessione– potrebbe offrire nuovi spunti interpretativi di natura socio-antropologica per la vexata quaestio dell’augusteismo dell’opera ovidiana.

Maintenance of pluripotency is a multifactorial process in which NF-κB is a negative regulator. Our previous work identified a chromatin role for IκBα, the master regulator of NF-κB signaling, that is critical for the proper regulation of various tissue stem cells. Here, we found that IκBα accumulates specifically in the chromatin fraction of pluripotent embryonic stem cells. IκBα depletion does not affect NF-kB-dependent transcription, but causes a profound epigenetic rewiring in pluripotent stem cells, including alterations in H3K27me3, a histone mark catalyzed by Polycomb repression complex 2. Chromatin changes induced by IκBα depletion affect a subset of pluripotency genes and are associated with altered gene transcription. At the cellular level, IκBα-deficient embryonic stem cells are arrested in a naive pluripotency state when cultured in serum/LIF conditions and fail to exit pluripotency under differentiation conditions. By constructing separation-of-function mutants, we show that the effects of IκBα in regulating stem cell pluripotency are NF-κB-independent, but mainly rely on its chromatin-related function. Taken together, our results reveal a novel mechanism by which IκBα participates in the regulation of the pluripotent state of embryonic stem cells and shed light on the interplay between inflammatory signals and the regulation of pluripotency.
Mettl5 coordinates protein production and degradation of PERIOD to regulate sleep in Drosophila
Authors: Wu Xiaoyu , Yang Xingzhuo , Fu Tiantian , Rong Yikang S , Du Juan
Published: January 2025

Sleep is crucial for animal physiology, primarily governed by the brain, and disruptions are prevalent in various brain disorders.
Mettl5
, associated with intellectual disability (ID) often accompanied by sleep disturbances, remains poorly understood in its role causing these disorders. Previous research demonstrated that Mettl5 forms a complex with Trmt112, influencing rRNA methylation. In our study, we explored sleep phenotypes due to
Drosophila Mettl5
mutations. Rescue experiments pinpointed
Mettl5
’s predominant role in neurons and glia marked by
Mettl5
-Gal4 in sleep regulation. Notably, a
Trmt112
mutation mirrored these sleep disturbances, implicating translational regulation via the Mettl5/Trmt112 complex. Subsequent RNA-seq and Ribo-seq analyses unveiled downstream events from

Mettl5
1bp

mutations, revealing altered expression levels of proteasome components and Clock genes. Rescue experiments confirmed that the net increased PERIOD protein is responsible for the sleep phenotype. This investigation sheds light on ribosome, clock genes, and proteasome interplay in sleep regulation, underscoring protein synthesis and degradation’s integrative role. These findings could potentially provide an example of
in vivo
study of the function of rRNA methylation, expand our understanding of the role of protein homeostasis in sleep and inspire explanations on the ID related sleep phenotypes.
Mutations that prevent phosphorylation of the BMP4 prodomain impair proteolytic maturation of homodimers leading to early lethality in mice
Authors: Kim Hyung-seok , Sanchez Mary , Silva Joshua , Schubert Heidi L , Dennis Rebecca , Hill Christopher P , Christian Jan L
Published: January 2025

Bone morphogenetic protein4 (BMP4) plays numerous roles during embryogenesis and can signal either as a homodimer, or as a more active BMP4/7 heterodimer. BMPs are generated as inactive precursor proteins that dimerize and are cleaved to generate the bioactive ligand and inactive prodomain fragments. In humans, heterozygous mutations within the prodomain of BMP4 are associated with birth defects. We studied the effect of two of these mutations (p.S91C and p.E93G), which disrupt a conserved FAM20C phosphorylation motif, on ligand activity. We compared the activity of BMP4 homodimers or heterodimers generated from BMP4, BMP4
S91C
or BMP4
E93G
precursor proteins in
Xenopus
embryos and found that these mutations reduce the activity of BMP4 homodimers but not heterodimers. We generated

Bmp4
S91C

and

Bmp4
E93G

knock-in mice and found that

Bmp4
S91C/S91C

mice die by E11.5 and display reduced BMP activity in multiple tissues including the heart at E10.5. Most

Bmp4
E93G/E93G

mice die before weaning and

Bmp4
-/E93G

mutants die prenatally with reduced or absent eyes, heart and ventral body wall closure defects. Mouse embryonic fibroblasts (MEFs) isolated from

Bmp4
S91C

and

Bmp4
E93G

embryos show accumulation of BMP4 precursor protein, reduced levels of cleaved BMP ligand and reduced BMP activity relative to MEFs from wild type littermates. Because
Bmp7
is not expressed in MEFs, the accumulation of unprocessed BMP4 precursor protein in mice carrying these mutations most likely reflects an inability to cleave BMP4 homodimers, leading to reduced levels of cleaved ligand and BMP activity in vivo. Our results suggest that phosphorylation of the BMP4 prodomain is required for proteolytic activation of BMP4 homodimers, but not heterodimers.
Zebrafish live imaging reveals only around 2% rather than 50% of motor neurons die through apoptosis during early development
Authors: Jia Hao , Yang Hongmei , Luo Kathy Qian
Published: January 2025

It is widely accepted that neurons will die through apoptosis if they cannot receive enough growth factors during development of vertebrates; however, there is still no real-time observation showing this dying process in live animals. Here, we generated sensor zebrafish achieving live imaging of motor neuron apoptosis at single-cell resolution. Using these sensor zebrafish, we observed for the first time that in an apoptotic motor neuron, caspase-3 activation occurred quickly within 5-6 min and at the same time between the cell body and axon. Interestingly, we found that only around 2% of motor neurons died during zebrafish early development, which is much lower than the generally believed 50% cell death occurred in embryonic stage of vertebrates. Our data also showed that most of the apoptotic bodies of these dead motor neurons were not cleared by macrophages. These sensor zebrafish can serve as powerful tools to study motor neuron apoptosis

This study evaluated the effectiveness of arbuscular mycorrhizal fungi (AMF) species, including Funneliformis mosseae (FM), Rhizophagus intraradices (RI), Claroideoglomus etunicatum (CE), and a Mycorrhizal mix (MM) comprising these three species, on pepper plants (Capsicum annuum L.) inoculated with two isolates of Fusarium solani (48-F. solani and 18-F. solani) and two isolates of Fusarium mix (50-F. mixture and 147-F. mixture). Analysis of variance (ANOVA)-Tukey statistics revealed that the effects of AMF inoculations on morphological parameters, disease severity, root colonization, and total spore numbers in pathogen-infected plants varied significantly depending on the AMF species and pathogen group. AMF colonization significantly reduced disease severity, with disease inhibition (DI) reaching up to 58%, depending on the specific pathogen. However, there were a few instances where the application of AMF did not lead to a reduction in disease severity. Single AMF species were more effective in enhancing the growth of pathogen-treated host plants and suppressing disease compared to the mixed AMF. The mixed AMF was only more effective in balancing pathogen-induced decreases in plant nutrients (Copper (Cu), Magnesium (Mg), Zinc (Zn), and Phosphorus (P)). Among the compared mycorrhizae, C. etunicatum (CE) was the most effective in disease suppression due to its relatively more positive effects on plant root structure, increasing root fresh weight by up to 49% in the CE+pathogen plant group compared to the control group. Root colonization rates were generally higher in plants treated with both mycorrhiza and pathogens compared to plants treated with mycorrhiza alone. Overall, the curative effects of AMFs on plants following pathogen application varied concurrently with disease severity rates caused primarily by pathogens. AMFs demonstrated greater efficacy in combating 18-F. solani, which causes less severe plant disease. However, the effectiveness of AMFs was comparatively lower against 48-F. solani and 147-F. mix., which cause more severe plant disease. This indicates that the efficacy of AMFs varies depending on the specific strain of Fusarium solani, with better results observed against strains that cause less severe plant disease.

Introduction: Flatfoot, or pes planus, is a postural deformity resulting from the inadequate development of the Medial Longitudinal Arch (MLA) of the foot. Generalised ligament laxity is the most important aetiological factor among various predisposing factors. Previous research has explored these conditions independently rather than investigating their potential association. This study focuses on understanding how generalised ligament laxity contributes to flexible flatfoot, which could provide valuable insights that have not been thoroughly explored in paediatric and adolescent populations.

Aim: To determine the association between flexible flatfoot and generalised ligament laxity in paediatric and adolescent populations.

Materials and Methods: This case-control study was conducted on 180 patients attending the Physical Medicine and Rehabilitation (PMR) Outpatient Department (OPD), aged 5 to 19 years, from September 2019 to March 2021. Footprints were taken from the subjects and a flatfoot assessment was performed using Staheli’s plantar arch index. The Jack test was conducted in all flatfoot subjects to exclude rigid flatfoot. All patients with flexible flatfoot were enrolled as cases, while those without flatfoot were enrolled in the control group. Both groups were further evaluated using the Beighton Score for the presence of generalised ligament laxity and results were recorded. Demographic factors were expressed as frequencies, and quantitative data were presented as median with 25th and 75th percentiles (IQR=interquartile range). Differences in qualitative variables between the groups were analysed using the Chi-square test.

Results: Out of the 180 subjects, 126 (70%) were male, and the majority, 108 (60%), were aged 11 to 19 years, with a mean ± SD age of 11.46±3.1 years. The proportion of ligament laxity was higher in cases 30 (41.67%) than in controls 20 (18.52%), and this association was statistically significant (p-value=0.016). Patients with flatfoot had a 3.14 times higher chance of having ligament laxity than those lacking flatfoot, which was statistically significant.

Conclusion: Children and adolescents with increased generalised ligament laxity are more predisposed to the development of flexible flatfoot compared to those without ligament laxity.

Background: Bloodborne infections (BBI) are caused by pathogens such as microorganisms carried via blood, such as bacteria or viruses capable of causing diseases that alter the normal state of the human body. The most common BBIs are syphilis, HIV, HPTLV-1, HBV, and HCV.
Objectives: To determine the prevalence, level of awareness, and knowledge of some blood-borne infections among students in the College of Health Sciences, LAUTECH, Ogbomoso. South-western Nigeria.    
Methods: A total number of 84 subjects (33 females and 51 males) were recruited. A self-structured questionnaire was used to obtain socio-demographic data and research questions. Blood was collected and screened, using an enzyme-linked immunosorbent assay specific for each blood-borne infection (Syphilis, Hepatitis B, Hepatitis C, HIV, and HTLV-1). The data obtained were analysed using Statistical Package for Social Sciences version 25 with the result presented in tables and charts.
Results: The prevalence includes 4.8% syphilis, 3.8% Hepatitis B, 1.2% Hepatitis C and 1.2% HIV. A high level of awareness of these infectious diseases was observed (86.9% for Syphilis, 77.4% for Hepatitis B, 71% for Hepatitis C, 89.3% for HIV, and 75% for HTLV-1) and a high knowledge of the causes and transmission of these blood-borne infections.
Conclusion: The prevalence of bloodborne infections is relatively low among the subjects as reported in these findings, despite this, it is very important to raise the awareness level of BBIs in institutions and communities to continue it downtrend prevalence and occurrence in the population.

The present investigation was conducted to estimate the genetic variability, heritability and genetic advance of genotypes of grain amaranth during kharif, 2022 at Agricultural Research Station, Tornala. Fifty nine genotypes of grain amaranth along with 4 checks (Suvarna, BGA-2, GA-5 and RMA 7) were evaluated in an augmented block design for access their performances. High phenotypic and genotypic coefficient of variation were observed for grain yield/plant (82.73/82.70), no. of spikelets/ plant (62.41/62.36), inflorescence length (49.72/49.66), plant height (41.54/41.47) and days to 50% flowering (21.78/21.66) indicating the presence of high variability in germplasm for selection. The characters viz., days to 50% flowering, plant height, inflorescence length, no. of spikelets/ plant and yield/plant expressed high heritability coupled with high genetic advance as percent of mean, which indicates preponderance of additive gene action in controlling the traits. Hence, the characters having high GCA & PCA can be relied upon and simple selection can be practiced for further improvement. Based on the performance, genotypes SKGPA183, EC322998, IC 551493, IC 551496 and IC 551499 have been found superior among the genotypes which can be used in breeding programmes for crop improvement.

Aims: During production, root-knot nematodes of the Meloidogyne genus, probably the most harmful, attack tomatoes. Given the harmful effect of certain nematicides used to control this nematode, the use of plant extracts could be an alternative for sustainable tomato production. The aim of this study was to evaluate the efficacy of neem and castor leaf extracts on root-knot nematodes in the field.
Place and Study Duration: Côte d’Ivoire, from April to August 2023.
Methodology: A plot previously infested with root-knot nematodes set up using a randomized complete block design. Neem and castor extracts are applied at a dose 100 g per tomato plant and furasol at 5 g, planted once a month until harvest. The density of root-knot nematodes was estimated in the soil each month before extract application and in tomato roots at harvest. Parameters such as severity and prevalence of galls, nematode density in soil and roots, plant height and fruit yield were measured during the study.
Results: The prevalence and severity of root galls on tomato plants were statistically identical on plants treated with furasol and castor (P>0,05). The results showed that neem and castor extracts had similar effects to furasol on tomato plants regarding plant height (from 72,40 ± 18,38 to 78,40 ± 11,27) and fruit yield (from 4,20 ± 0,63 to 4,80 ± 0,42). These plant extracts induced a low rate of multiplication of these nematodes in the same way as furasol, and reduced the number of nematodes in the soil and roots of treated tomato plants.
Conclusion: The results obtained in this study are encouraging, and the long-term use of these plant extracts could be a sustainable control method against root-knot nematodes.
