Environmental degradation poses a significant challenge in many developing countries, as they heavily rely on fossil fuels to drive economic activities. The transition towards renewable energy is crucial to mitigate ecological depletion, yet numerous Asian developing countries may struggle to achieve the desired levels of renewable energy adoption due to financial constraints. Foreign aid in the energy sector can expedite this transition process.

A pot study that had earlier been investigated TB mono and blended with CH, CB and NZ on the immobilization of Pb, Cu Cd, and Zn by Chinese cabbage. Maize crop in the rotation was selected as test plant to assess the residual impact of amendments on stabilization of Pb, Cu Cd, and Zn in mine polluted (M-P), smelter heavily and low polluted (S-HP and S-LP, respectively) soils.

The ability to predict which infants will respond to indomethacin could spare some from the risks of unnecessary medications. Our objective was to determine if indicators of acid-base homeostasis could predict response to indomethacin treatment for ductal closure, and thus help guide treatment decisions.

Total polyphenols (TP), total flavonoids (TF), the concentration of allicin, ethylene production and the antioxidant potential were evaluated and analyzed by using four different assays.

This is mostly due to a dearth of clinical studies performed in pediatric patients. In Marfan syndrome, the major sources of morbidity and mortality relate to the cardiovascular system.

Acute chest pain with very elevated troponin level and abnormal EKG in adult population is considered sine qua non to acute coronary syndrome (ACS) unless proved otherwise. Similar presentation in adolescent population is seen less often but raises suspicion for ACS. Most common etiology for chest pain with cardiac enzyme elevation in adolescent population is usually viral myopericarditis.

Acute chest pain with elevated troponin and CK-MB levels and focal ST elevation on electrocardiogram is considered to be myocardial infarction unless proven otherwise. The cardiac enzymes can be elevated in other etiologies of chest pain including myopericarditis, pulmonary embolism, acute rheumatic fever, and trauma. Therefore, patients presenting with chest pain and elevated cardiac enzymes should be carefully evaluated for other etiologies after ruling out acute coronary process.

Although isolated LBBB is a conduction abnormality found in some healthy adults, it has not been reported in pediatric population. We report a 2-year-old, healthy African American female who was incidentally discovered to have isolated LBBB that has persisted in a follow-up of 3 years.

This includes the relatively new but contentious prophylactic antibiotic regimen. However, these cases still continue to pose a challenge in the adult and pediatric populations.

This report discusses the angiographic and hemodynamic features of LSVC when it is the only drainage route from a blind coronary sinus. A retrograde flow in the LSVC seen by Doppler ultrasonography should raise the suspicion of this diagnosis.

Background: Fetal supraventricular tachycardia causes significant fetal and neonatal morbidity and mortality. Prenatal analysis and postnatal confirmation of fetal supraventricular tachycardia mechanisms have been limited.
Objective: Early in cardiac development, regulation of cytosolic Ca2+ has been thought to depend primarily on sarcolemmal Ca2+ transport. We hypothesized that perturbation of cytosolic Ca2+ in the embryonic ventricle would result in a change in ventricular relaxation which could be quantified by a monoexponential model. We reasoned that since it has been difficult to selectively block the Na(+)-Ca2+ exchanger in vivo, that blockade of Na+ (lidocaine) or Ca2+ (verapamil) channels in the embryonic heart may perturb cytosolic Ca2+ and thereby alter ventricular relaxation.
