Haymana, Ankara
Haymana is a municipality and district of Ankara Province, Turkey. Its area is 2,164 km2, and its population is 26,016 (2022). It is 72 km south of the capital, Ankara. Its elevation is 1200 m. Etymology According to the 1074-dated dictionary Dīwān ul-Lughat al-Turk, haymana means prairie in Turkish. History Archaeological excavations were launched in ''Gavur Kalesi'', a castle situated in the village of Dereköy, in the years 1930 and 1998. The results showed that it was an important Phrygian settlement. Besides, the tumuli located in Türkhöyük and Oyaca villages prove that the area was also inhabited during the Hittite period. After the periods of the Roman and Byzantine rule, the area was captured by the Seljuk Turks in 1127. After the Battle of Köse Dağ it came under Ilkhanate control for a while. In the mid 14th century the area was annexed by the Ottomans. After a brief period of Timurid rule in the wake of the Battle of Ankara in 1402, it was re-capture ...

Embryo
An embryo ( ) is the initial stage of development for a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell. The resulting fusion of these two cells produces a single-celled zygote that undergoes many cell divisions that produce cells known as blastomeres. The blastomeres (4-cell stage) are arranged as a solid ball that when reaching a certain size, called a morula, (16-cell stage) takes in fluid to create a cavity called a blastocoel. The structure is then termed a blastula, or a blastocyst in mammals. The mammalian blastocyst hatches before implantating into the endometrial lining of the womb. Once implanted the embryo will continue its development through the next stages of gastrulation, neurulation, and organogenesis. Gastrulation is the formation of the three germ layers that will form all of the different parts of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Implantation (human Embryo)
Implantation, also known as nidation, is the stage in the mammalian embryonic development in which the blastocyst hatches, attaches, adheres, and penetrates into the endometrium of the female's uterus. Implantation is the first stage of gestation, and, when successful, the female is considered to be pregnant. An implanted embryo is detected by the presence of increased levels of human chorionic gonadotropin (hCG) in a pregnancy test. The implanted embryo will receive oxygen and nutrients in order to grow. For implantation to take place the uterus must become receptive. Uterine receptivity involves much cross-talk between the embryo and the uterus, initiating changes to the endometrium. This stage gives a synchrony that opens a window of implantation that enables successful implantation of a viable embryo. The endocannabinoid system plays a vital role in this synchrony in the uterus, influencing uterine receptivity, and embryo implantation. The embryo expresses cannabinoi ...

Labiaplasty
Labiaplasty (also known as labioplasty, labia minora reduction, and labial reduction) is a plastic surgery procedure for creating or altering the labia minora (inner labia) and the labia majora (outer labia), the folds of skin of the human vulva. It is a type of vulvoplasty. There are two main categories of women seeking cosmetic genital surgery: those with conditions such as intersex, and those with no underlying condition who experience physical discomfort or wish to alter the appearance of their vulvas because they believe they do not fall within a normal range. The size, colour, and shape of labia vary significantly, and may change as a result of childbirth, aging, and other events. Conditions addressed by labiaplasty include congenital defects and abnormalities such as vaginal atresia (absent vaginal passage), Müllerian agenesis (malformed uterus and fallopian tubes), intersex conditions (male and female sexual characteristics in a person); and tearing and stretchin ...

Orthognathic Surgery
Orthognathic surgery (), also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot be treated easily with braces, as well as the broad range of facial imbalances, disharmonies, asymmetries, and malproportions where correction may be considered to improve facial aesthetics and self-esteem. The origins of orthognathic surgery belong in oral surgery, and the basic operations related to the surgical removal of impacted or displaced teeth – especially where indicated by orthodontics to enhance dental treatments of malocclusion and dental crowding. One of the first published cases of orthognathic surgery was the one from Dr. Simon P. Hullihen in 1849. Originally coined by Harold Hargis, it was more widely popul ...

Facial Nerve Paralysis
Facial nerve paralysis is a common problem that involves the paralysis of any structures innervated by the facial nerve. The pathway of the facial nerve is long and relatively convoluted, so there are a number of causes that may result in facial nerve paralysis. The most common is Bell's palsy, a disease of unknown cause that may only be diagnosed by exclusion of identifiable serious causes. Signs and symptoms Facial nerve paralysis is characterised by facial weakness, usually only on one side of the face, with other symptoms possibly including loss of taste, hyperacusis and decreased salivation and tear secretion. Other signs may be linked to the cause of the paralysis, such as vesicles in the ear, which may occur if the facial palsy is due to shingles. Symptoms may develop over several hours. Acute facial pain radiating from the ear may precede the onset of other symptoms. Causes Bell's palsy Bell's palsy is the most common cause of acute facial nerve paralysis. Th ...

Facial Muscles
The facial muscles are a group of striated skeletal muscles supplied by the facial nerve (cranial nerve VII) that, among other things, control facial expression. These muscles are also called mimetic muscles. They are only found in mammals, although they derive from neural crest cells found in all vertebrates. They are the only muscles that attach to the dermis. Structure The facial muscles are just under the skin ( subcutaneous) muscles that control facial expression. They generally originate from the surface of the skull bone (rarely the fascia), and insert on the skin of the face. When they contract, the skin moves. These muscles also cause wrinkles at right angles to the muscles’ action line. Nerve supply The facial muscles are supplied by the facial nerve (cranial nerve VII), with each nerve serving one side of the face. In contrast, the nearby masticatory muscles are supplied by the mandibular nerve, a branch of the trigeminal nerve (cranial nerve V). List of muscl ...

Tissue Engineering
Tissue engineering is a biomedical engineering discipline that uses a combination of cells, engineering, materials methods, and suitable biochemical and physicochemical factors to restore, maintain, improve, or replace different types of biological tissues. Tissue engineering often involves the use of cells placed on tissue scaffolds in the formation of new viable tissue for a medical purpose, but is not limited to applications involving cells and tissue scaffolds. While it was once categorized as a sub-field of biomaterials, having grown in scope and importance, it can be considered as a field of its own. While most definitions of tissue engineering cover a broad range of applications, in practice, the term is closely associated with applications that repair or replace portions of or whole tissues (i.e. organs, bone, cartilage, blood vessels, bladder, skin, muscle etc.). Often, the tissues involved require certain mechanical and structural properties for proper functioning. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breast Reconstruction
Breast reconstruction is the surgical process of rebuilding the shape and look of a breast, most commonly in women who have had surgery to treat breast cancer. It involves using autologous tissue, prosthetic implants, or a combination of both with the goal of reconstructing a natural-looking breast. This process often also includes the rebuilding of the nipple and areola, known as nipple-areola complex (NAC) reconstruction, as one of the final stages. Generally, the aesthetic appearance is acceptable to the woman, but the reconstructed area is commonly completely numb afterwards, which results in loss of sexual function as well as the ability to perceive pain caused by burns and other injuries. Timing Breast reconstruction can be performed either immediately following the mastectomy or as a separate procedure at a later date, known as immediate reconstruction and delayed reconstruction, respectively. The decision of when breast reconstruction will take place is patient-speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Associate Professor
Associate professor is an academic title with two principal meanings: in the North American system and that of the ''Commonwealth system''. In the ''North American system'', used in the United States and many other countries, it is a position between assistant professor and a full professorship. In this system, an associate professorship is typically the first promotion obtained after gaining a faculty position, and in the United States it is usually connected to tenure. In the ''Commonwealth system'', the title associate professor is traditionally used in place of reader in certain countries.UK Academic Job Titles Explained academicpositions.com Like the reader title it ranks above [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
