citrus tristeza virus (ctv) is among the most destructive pathogens of citrus and causes substantial economic losses in citrus-growing industry worldwide. considering recent distribution of this pathogen and its capability of transmission by existing aphid vectors in iran, detection of this virus is enforceable for controlling the damage caused by this pathogen in iran, as one of the major citr...

Intrafraction motion during intensity-modulated radiation therapy can cause differences between the planned and delivered patient dose. The magnitude of these differences is dependent on a number of variables, including the treatment modality. This study was designed to compare the relative susceptibility of plans generated with three different treatment modalities to intrafraction motion. The ...

BACKGROUND Intermediate- to-high-risk prostate cancer can locally invade seminal vesicle (SV). It is recommended that anatomic proximal 1-cm to 2-cm SV be included in the clinical target volume (CTV) for definitive radiotherapy based on pathology studies. However, it remains unclear whether the pathology indicated SV extent is included into the CTV defined by current guidelines. The purpose of ...

PURPOSE Temporary tissue expanders (TTE) with an internal magnetic metal port (IMP) have been increasingly used for breast reconstruction in post-mastectomy patients who receive radiation therapy (XRT). We evaluated XRT plans of patients with IMP to determine its effect on XRT dose distribution. METHODS AND MATERIALS Original treatment plans with CT simulation scans of 24 consecutive patients...

Accurate delineation of clinical target volume (CTV) is critical in the effective management of squamous cell carcinoma (SCC) of esophagus using radiation therapy. Accurate delineation may improve the probability of local control and reduce the risk of complications. However, there are no consistent standards on the proper size of the margins added to the gross tumor volume (GTV). Different ins...

Cutthroat trout virus (CTV) is a non-pathogenic fish virus belonging to the Hepeviridae family, and it is distantly related to hepatitis E virus (HEV). Here, we report the development of an efficient cell culture system where CTV can consistently replicate to titers never observed before with a hepevirus. By using the rainbow trout gill (RTGill-W1) cell line, CTV reaches 1010 geq/mL intracellul...

A new strategy to obtain fluorescent cyclotriveratrylene (CTV) probes is proposed. The key intermediate, a triiodo CTV, is prepared in 3 steps with 47% overall yield. The whole synthesis requires only one purification step. The potential of this triiodo CTV as an intermediate is illustrated through the synthesis of a fluorescent phosphorylated probe that is able to bind choline and acetylcholin...

In Bangladesh, citrus is an important fruit crop that becoming more commonly cultivated in commercial plantations. March 2019, we observed yellowing, vein clearing, and mild mosaic symptoms citron (Citrus medica). Based on systematic serological molecular analyses of the symptomatic leaf samples, Citrus tristeza virus (CTV) was identified. To best our knowledge, this first report CTV any Bangla...

Six severe and six mild Florida isolates of citrus tristeza virus (CTV) were used to evaluate the transmission efficiency of the virus from grapefruit seedlings by single brown citrus aphids (Toxoptera citricida Kirkaldy) (BrCA) from colonies initiated by aphids obtained from citrus groves in Fort Pierce, Fla. The transmission rate to 2120 receptor plants [‘Mexican’ lime (Citrus aurantifolia)] ...
