Different uses of angiostensin - converting enzyme inhibitors

The renin-angiotensin-a/dosterone system plays a keyrole in the regulation of fluid and electrolyte balance. Angiotensinconverting enzyme inhibitors (ACE/s) inhibit angiotensin-converting enzyme and have been shown to be effective in many cardiovascular diseases, including hypertension, heart failure, myocardial infarction and diabetic nephropathy. ACE/s are the most effective class of drugs in reversing left ventricular hypertrophy due to hypertension. ACE/s improve cardiac function and reduce mortality in congestive heart failure and after myocardial infarction. ACE/s should be considered in diabetics with microalbuminuria or albuminuria, especially in the presence of hypertension. There are many different ACE/s available now; they are largely similar in their effects, but differ particularly in pharmacokinetics. Choice will depend on previous experience, availability and price. There are a number of side-effects associated with ACEIs; periodic monitoring of renal function and electrolytes is required.published_or_final_versio

Sharp Cusa and Becker-Stark inequalities

We determine the best possible constants θ,ϑ,α and β such that the inequalities ((2+cosx)/3)^θ < sinx/x < ((2+cosx)/3)^ϑ and ((π^2)/(π^2-4×^2))^α < tan×/× < ((π^2)/(π^2-4×^2))^β are valid for 0 < × < π/2. Our results sharpen inequalities presented by Cusa, Becker and Stark.published_or_final_versio

The sonographic appearance and obstetric management of placenta accreta

Placenta accreta is a condition of abnormal placental implantation in which the placental tissue invades beyond the decidua basalis. It may invade into or even through the myometrium and adjacent organs, such as the urinary bladder. The incidence has been rising in recent years. It is one of the important obstetric complications nowadays, leading to significant maternal morbidity and mortality. In the past, this condition was often diagnosed at the time of delivery when massive and unexpected hemorrhage occurred. Hysterectomy, associated with significant physical and psychological consequences, was usually the only management option. As more obstetricians have become aware of this condition, early identification with antenatal imaging diagnostic technology has become possible. Ultrasound scan plays an important role in the antenatal diagnosis. Various sonographic features with different specificity and sensitivity have been described in the literature. In equivocal cases, magnetic resonance imaging may be helpful. With such information, more accurate counseling can be offered to the mothers and their families before delivery. The delivery can also be arranged at a favorable time and in an institution where multidisciplinary support is available. Input from a hematologist, interventional radiologist, intensive care physician, urology surgeon, and/or other specialist are desirable. Apart from hysterectomy, various forms of conservative management can also be considered when the diagnosis is made prior to delivery. Fertility can therefore be preserved. After delivery, with or without hysterectomy performed, psychological support to the mothers and their families is essential.published_or_final_versio
