The lacrimal gland is a diamond-shaped, tubuloalveolar gland that secretes the serous component of tears. A four-year-old female crossbreed sheep suffering from left eye protrusion was referred to a Veterinary Hospital. Ophthalmic examination revealed epiphora, superficial ulcerative keratitis, corneal edema and neovascularisation. Moreover, ultrasound examination showed a large heterogeneous m...
An eight-month-old, female Cane Corso bitch was presented for treatment following complaint of protrusion of oedematous tissue through the vulva lips one week after the commencement of the oestrous cycle. Clinical examination revealed a pear-shaped fibrous vaginal mass measuring about 5 cm in diameter. Ultrasonography identified a single follicular cyst in the left ovary and vaginal smear cytol...
The room temperature deposition of self-assembling silica nanoparticles onto D-shaped optical fibres ("D-fibre"), drawn from milled preforms fabricated by modified chemical vapour deposition (MCVD), is studied. Vertical dip-and-withdraw produces tapered layers, with one end thicker (surface coverage >0.85) than the other, whilst horizontal dip-and-withdraw produces much more uniform layers over...
Normal level of eye protrusion is different in various populations and many factors such as age, sex, race, refractive error, and anthropometric characteristics affect it. There are limited studies in Iran about the normal amount of eye protrusion in healthy population and normal exophthalmometric values. In this meta-analysis, taking into account the results of the 4 studies, we decided to obt...
background: intervertebral disc herniation has two common types, extrusion and protrusion, which may affect the adjacent vertebrae.in addition, it is associated with significant signal changes in t1 mri (short tr/te) and t2 mri (long tr/te). methods: the present study is a cross-sectional analytic one, in which sampling was performed retrospectively. cases were randomly selected from the pati...
Protrusions are deformations that form at the surface of living cells during biological activities such as cell migration. Using combined optical tweezers and fluorescent microscopy, we quantified the mechanical properties of protrusions in adherent human embryonic kidney cells in response to application of an external force at the cell surface. The mechanical properties of protrusions were ana...
Growth cone advance depends on coordinated membrane protrusion and adhesion to the extracellular matrix. Although many studies have addressed the mechanisms responsible for membrane protrusion, the assembly of integrin-dependent adhesion sites known as point contacts remains poorly understood in growth cones. We show balanced Rac1 activity controls both leading edge protrusion and point contact...
Neither the P32-phosphate nor the S35-sulfate were metabolized by intact seeds until after radicle protrusion (15 to 18 hours after beginning of imbibition). Punctured seeds, however, metabolized the radioactive phosphate or sulfate within 3 hours after the beginning of imbibition. We concluded that the coats surrounding the embryo are impermeable to phosphate and sulfate ions. Most of the orga...
