Variations in Responses to the Superovulatory Hormone Doses using Cross bred HF Dairy Cows in Ethiopia

Hamid Jemal, Alemayehu Lemma, Tamrat Degefa

World Scientific News > 2021 > 154 > 66-75

Response to the superovulatory hormone treatments varied for the type of breed and doses of superovulatory hormone used. Ovarian response of 42 cross bred HF (50%, 75%) and pure dairy cows were evaluated based on ultrasonographic count of CL and embryo recovery for quality assessment. Ovarian response rate was significantly higher (P<0.05) in the crossbreds than in the pure bred cows. The maximum...

M. Boy Adiluhung, Indah Riyantini, Sunarto Sunarto, Ibnu Faizal

World Scientific News > 2021 > 154 > 48-65

Green turtles (Chelonia mydas (Linnaeus, 1758)) take advantage of the sand beach area as a stopover and carry out biological activities such as nesting and laying eggs. Pangumbahan Beach is one of the green turtle conservation places which is directly adjacent to the Indian Ocean. Tides affect physical processes such as the flushing of seawater on to the coast due to waves and flushing of water masses...

Vegetative Propagation: A Unique Technique of Improving Plants Growth

B. F. Awotedu, T. O. Omolola, A. O. Akala, O. L. Awotedu, more

World News of Natural Sciences > 2021 > 35 > 83-101

Vegetative propagation is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant. Different methods of propagation can be used for plants because they respond differently. Based on plant growing uniformly, increasing the production of these plants, their resistance to pest and diseases, early bearing of fruits and having some certain traits...

Coronary bifurcations – anatomy, physiology and treatment with selected aspects of left main stem bifurcation

Wojciech Milejski, Beata Morawiec, Jerzy Sacha, Ewa Nowalany-Kozielska, more

Annales Academiae Medicae Silesiensis > 2021 > 75 > 24-32

Coronary bifurcation remains a unique region of the coronary tree. The specific anatomy and blood flow determine the complex mechanisms of atherosclerotic plaque location. The treatment strategy should be chosen with caution as the failure of percutaneous coronary interventions (PCI) may expose a significantly larger area of the myocardium to ischemia than in the case of single vessel PCI. In order...

R. Sakthi Sankari, M. P. Syed Ali Nisaya

World Scientific News > 2021 > 155 > 140-154

Let G=(V,E) be a graph with p vertices and q edges. A second order triangular graceful labeling of a graph G is an one to one function φ:V(G)→{0,1,2,…,B_q} where B_q is the qth second order triangular number, ie., B_q=1/6 q(q+1)(2q+1), that induces a bijection φ^*:E(G)→{B_1,B_2,…,B_q} of the edges of G defined by φ^* (uv) =|φ(u)-φ(v)| ∀ e=uv ∈E(G). A graph which admits such labeling is called a second...

Centrally acting cholecystokinin induces depressor circulatory effects in haemorrhage-shocked rats

Karolina Jasikowska, Magdalena A. Zając, Jerzy Jochem

Annales Academiae Medicae Silesiensis > 2021 > 75 > 18-23

INTRODUCTION: Cholecystokinin (CCK) is a peptide gastrointestinal hormone involved in the stimulation of lipid and protein digestion as well as a neurotransmitter/neuromodulator in the central nervous system. After intravenous administration, it induces a resuscitating effect in rats subjected to haemorrhagic shock. Since CCK is able to directly and indirectly affect the cardiovascular centre function,...

World Scientific News > 2021 > 155 > 113-128

A centered triangular sum labeling of a graph G is a one-to-one function f : V (G) → N ∪{0} that induces a bijection f *: E(G) →{B_1 〖,B〗_2,…B_q} of the edges of G defined by f * (uv) = f(u) + f(v), for all e = uv ∊ E(G). The graph which admits such labeling is called a centered triangular sum graph.

Critical Care Innovations > 2021 > 4 > 1 > 44-47

One of the most commonly affected organ systems by SARS-CoV-2 virus is the respiratory system. Major challenge with coronavirus disease is managing the pulmonary complications. Role of non-invasive ventilation in patients of coronavirus disease 2019 (COVID 19) has been questioned in spite of evidence showing its use in acute hypoxemic respiratory failure. Patient selection is very important when using...
