the facial esthetics after orthodontic treatment and orthognathic surgery may be affected by the patient's natural head position. the purpose of this study was to evaluate the natural head position for the three skeletal classes of malocclusion.our sample consisted of 102 lateral cephalometric radiographs of patients aged 15 to 18 years; class i (n=32), class ii (n=40) and class iii (n=30). nin...

among the female sexual hormones, the estrogen and progesterone are of significant importance. these hormones are prescribed for the treatment of certain female genital system disorders as well as used in the synthesis of contraceptive drugs. it has been shown that administration of the above hor mones during early pregnancy may produce abortion in early gestational days. in the present investi...

The adenyl cyclase system has been the subject of great interest during the last few years, and many investigations have been made on several normal tissues and cells, many of which are target cells for hormones. However, little has been reported so far on tumor cells, some of which (e.g., Ehrlich tumor cells) are not known as target tissues for hor mones. In light of the recent findings (1, 2)...

We present the modeling technique we apply to analyse data of the ESO Coudé Echelle Spectrometer (CES) planet search program, in order to obtain high precision stellar radial velocity (RV) measurements. The detection of the Doppler reflex motion of a star due to an orbiting planet has so far been the most successful method to discover planetary companions to solar-type stars. The first extrasol...

AIM To use a novel computational approach, Key-string Algorithm (KSA), for the identification and analysis of arbitrarily large repetitive sequences and higher-order repeats (HORs) in noncoding DNA. This approach is based on the use of key string that plays a role of an arbitrarily constructed "computer enzyme". METHOD A cluster of novel KSA-related methods was introduced and developed on the...

Abstract This piece explores possible reasons for Lucilius’ suggestive reference to worms, emblemate uermiculato , in the famous comment (about speech arranged akin mosaics) which has survived from Book 2 of satirist. The fragment can be set metatextually amid other extracts Lucilius show poet's agency and skill, considered as having influenced aspects its own afterlife (especially Hor. Sat . 2...

BACKGROUND Low vitamin D status increases the risk of stress fractures. As ultraviolet (UV) light is required for vitamin D synthesis, low UV light availability is thought to increase the risk of vitamin D insufficiency and poor bone health. The purpose of this investigation was to determine if individuals with low UV intensity at their home of record (HOR) or those with darker complexions are ...
