Article Synopsis
  • The study investigates the heart's contractile reserve and how it is affected by β-adrenergic signaling, which traditionally increases heart rate and contractility during stress.
  • Researchers find that specific sites on the protein Rad, when modified by a process called phosphorylation, are essential for controlling calcium flow into heart cells (cardiomyocytes), impacting heart performance.
  • Mutations in Rad lead to significant decreases in heart function under stress and regular conditions, but introducing modified calcium-channel proteins can restore heart function, indicating potential for new heart treatments.

Our previous study indicated that there are at least 7 cardiovascular representation areas on the face, including the "Eyebrows", both sides of the "Nose", "Lelt Upper Lip" and the "Outside of the corner of both sides of the mouth," in addition to 2 areas in each hand. When there are cardiovascular problems, some of the heart representation areas of these areas often show the following changes: 1) Most distinctive visible changes such as the initial whitening with or without long white hair, then hair loss and complete disappearance of the hairs of the heart representation area of "Eyebrows" 2) Invisible biochemical changes that happen in heart representation areas at the "Left Upper Lips", 3) "Nose" below eye level as well as 4) "3rd segment of Middle Finger of Hands." Most distinctive visible & invisible changes are found in heart representation areas on the "Eyebrow", located nearest to the midline of face, where the color of the hairs becomes white compared with the rest of the Eyebrow.

The postdural puncture headache is a frequent iatrogenic complication due to an excessive leakage of cerebrospinal fluid. The leak through the dural perforation mainly depends on the size and design of the needle. The diagnostic is based on the notion of dural puncture, headache worsening in upright posture and other symptoms as neck stiffness, tinnitus, hypacusia, photophobia or nausea.

The determination of the prevalence of inherited hemoglobin (Hb) disorders in endemic areas is important in order to develop programs for their control and management. The aim of this study is to determine the prevalence of inherited Hb diseases in Guinea-Bissau which is situated on the west coast of Africa, between Senegal and Guinea. One thousand and fifty-seven blood samples were collected and analyzed with high performance liquid chromatography (HPLC) for detection of beta-thalassemia (thal) and Hb variants, and by gap polymerase chain reaction (gap-PCR) for the detection of deletions in the alpha-globin genes.
