PURPOSE: The study was performed to study the effect of cycloplegia on anterior chamber depth (ACD) in cataract eyes. One instrument (Lenstar) was used for all measurements. METHODS: Anterior chamber depth calculations were taken with the Lenstar in cataract eyes with a mean age of 71.9±8.8 years before instilling cycloplegic drops. Two drops of Tropicamide were then instilled in each eye and measurements were retaken between 30 to 45 min later. RESULTS: Cycloplegia with a mild agent used routinely in this practice location showed a statically significant effect on increasing ACD by 0...

Cell polarization is commonly used for the regulation of stem cell asymmetric division in both animals and plants. Stomatal development in Arabidopsis, a process that produces breathing pores in the epidermis, requires asymmetric cell division to differentiate highly specialized guard cells while maintaining a stem cell population [1, 2]. The BREAKING OF ASYMMETRY IN THE STOMATAL LINEAGE (BASL) protein exhibits a polarized localization pattern in the cell and is required for differential cell fates resulting from asymmetric cell division [3]...

Sequestrectomy alone represents a procedure for the treatment of lumbar disc herniation. For selected cases, an anulus closure device (ACD) can be implanted which may result in lower reoperation rates. However, comparative magnetic resonance imaging (MRI) changes and their clinical relevance of both procedures are unclear and have not been reported so far. Clinical and MRI data of patients after limited discectomy with ACD implantation (group ACD; N=45) and patients after sequestrectomy alone (group S; N=40) with primary lumbar disc herniation were compared retrospectively...

Asymmetric cell division (ACD) is utilized in many stem cell systems to produce two daughter cells with different cell fates. Despite the fundamental importance of ACD during development and tissue homeostasis, the nature of ACD is far from being fully understood. Step-by-step observation of events during ACD allows us to understand processes that lead to ACD. Here we describe examples of how we evaluate ACD in vivo using the Drosophila male germline stem cell system.

BACKGROUND: Reactions between nitric oxide (NO), nitrite (NO2(-) ), and unsaturated fatty acids give rise to electrophilic nitro-fatty acids (NO2 -FAs), such as nitro-oleic acid (OA-NO2 ) and nitro-linoleic acid (LNO2 ). Endogenous electrophilic fatty acids (EFAs) mediate anti-inflammatory responses by modulating metabolic and inflammatory signal transduction reactions. Hence, there is considerable interest in employing NO2 -FAs and other EFAs for the prevention and treatment of inflammatory disorders...

: BACKGROUND: Though the development and fitting of scleral contact lenses are expanding steadily, there is no simple method to provide scleral metrics for scleral contact lens fitting yet. The aim of this study was to establish formulae for estimation of the axial radius of curvature (ARC) of the anterior sclera using ocular biometric parameters that can be easily obtained with conventional devices. METHODS: A semi-automated stitching method and a computational analysis tool for calculating ARC were developed by using the ImageJ and MATLAB software...

Allergic contact dermatitis (ACD) represents a severe health problem with increasing worldwide prevalence. It is a T-cell-mediated inflammatory skin disease caused by chemicals present in the daily or professional environment. NiSO4 and 2,4-dinitrochlorobenzene (DNCB) are 2 chemicals involved in ACD. These contact sensitizers are known to induce an up-regulation of phenotypic markers and cytokine secretion in dendritic cells (DCs; professional APCs), leading to the generation of CD8(+) Tc1/Tc17 and CD4(+) Th1/Th17 effector T cells...

PURPOSE: Since age-related changes in lens elasticity and ciliary muscle contractility can affect how ocular parameters respond to cycloplegia, intraocular lens (IOL) power measurements calculated by formulas using anterior chamber depth (ACD), lens thickness (LT) or white-to-white (WtW) for effective lens position prediction can vary. In response, using swept-source optical biometry in pre-presbyopic and presbyopic eyes, we investigated changes in ocular parameters and IOL power calculations due to cycloplegia...

Anaemia is a condition in which the number of red cells necessary to meet the body's physiological requirements is insufficient. Iron deficiency anaemia (IDA) and the anaemia of chronic disease (ACD) are the two most common causes of anaemia worldwide; iron homeostasis plays a pivotal role in the pathogenesis of both diseases. An understanding of how iron studies can be used to distinguish between these diseases is therefore essential, not only for diagnosis but also in guiding management. This review will primarily focus on IDA and ACD; however iron overload in anaemia will also be briefly discussed...

In this study, we describe our diagnosis and treatment of two patients who presented with femoral vessel compression caused by a cystic lesion in the groin. One case was diagnosed as adventitial cystic disease (ACD) of the common femoral artery resulting in leg claudication and the other was diagnosed as a ganglion cyst (GC) causing femoral vein compression and unilateral leg swelling. The operative findings differed between these two cases with respect to the dissection of the cyst and femoral vessel, but the postoperative histological examination results were similar...

BACKGROUND: Angioseal, an arteriotomy closure device (ACD), functions as a collagen plug that physically closes arteriotomy sites and can simultaneously induce platelet activation and aggregation. When used 'on-label', the safety and efficacy profile of Angioseal is superior compared with those of other ACDs. However, Angioseal is sometimes deployed in less than ideal situations. Therefore, we sought to assess the safety and efficacy of 'off-label' Angioseal use in patients undergoing femoral arteriotomies...

The new phosphidosilicates Li2 SiP2 and LiSi2 P3 were synthesized by heating the elements at 1123 K and characterized by single-crystal X-ray diffraction. Li2 SiP2 (I41 /acd, Z=32, a=12.111(1) Å, c=18.658(2) Å) contains two interpenetrating diamond-like tetrahedral networks consisting of corner-sharing T2 supertetrahedra [(SiP4/2 )4 ]. Sphalerite-like interpenetrating networks of uniquely bridged T4 and T5 supertetrahedra make up the complex structure of LiSi2 P3 (I41 /a, Z=100, a=18.4757(3) Å, c=35...

BACKGROUND: As COBE Spectra has been replaced in many parts of the world, we describe a new protocol for low-density lipoprotein (LDL)-apheresis performed on familial hypercholesterolemia patients for the Spectra Optia platform. METHODS: For all procedures, after administering a bolus of heparin of 2,500 U, 10,000 U of heparin added to a 600 ml ACD-A bag was used as anticoagulant (AC). In a first phase (A), 16 apheresis procedures with COBE Spectra using an inlet:AC ratio of 25:1 were compared to 18 LDL-apheresis treatments with Spectra Optia at split Inlet:AC ratios of 16:1/18:1 or 20:1/25:1...

Adventitial cystic disease (ACD) of the common femoral vein is a rare vascular disorder. It becomes more difficult to recognize preoperatively especially when the femoral vein is affected. We report the case of a 62-year-old female patient who presented with a one-month history of painless swelling in her right lower extremity. She had no specific past medical history and no history of trauma, and had a full coagulopathy profile that was negative for any hypercoagulable syndrome. On examination, her lower right leg was significantly swollen with a palpable mass in her right inguinal region...

The main objective of our study was to assess density and diversity of rhizosphere (R) and endophytic (E) microorganisms associated with the halophyte S. europaea. Microorganisms were isolated from two saline sites (S1: 55dSm(-1), anthropogenic origin; S2: 112dSm(-1), natural salinity) located in central Poland and compared with microbial populations in the soil (S) using culture-independent (phospholipid fatty acids analysis, PLFA) and culture-dependent techniques. The endophytic and rhizosphere bacteria were identified and screened for nifH and acdS genes, and their metabolic properties were assessed...
