Soluble H2S widely exists in natural gas or oil potentially corroding oil/gas pipelines. Furthermore, it can affect the hydrate formation condition, resulting in pipeline blockage; the nucleation mechanism from mixed gas including H2S is still largely unclear. Molecular dynamics simulations were performed to reveal the effects of different initial mixed H2S/CH4 compositions on the hydrate nucleation and growth process. The geometric details of the nanobubbles and gas composition in the nanobubbles were analyzed; the size of the nanobubbles was found to decrease from 3.4 nm to 1.4 nm. With the increase in the initial H2S proportion, the diameter of the nanobubbles decreased; more guest molecules were dissolved in the water, which improved the initial concentration of guest molecules in the water. A multi-site nucleation process was observed, and separate hydrate clusters could grow independently until the simulation box limited their growth due to high local H2S concentration as a potential nucleation location. check details When the initial proportion of mixed gas approaches, H2S preferred to occupy and stabilize the incipient cage. Moreover, 512, 4151062, and 51262 cages accounted for approximately 95% of the first hydrate cage. Nucleation rates were shown to increase from 4.62 × 1024 to 9.438 × 1026 nuclei cm-3 s-1. The present high subcooling and H2S concentration provided a high driving force to promote mixed hydrate nucleation and growth. The proportion of cages occupied by H2S increased with increasing initial H2S proportion, but the largest enrichment factor of 1.38 occurred at 10% initial H2S/CH4 mixed gas.Pseudomyogenic hemangioendothelioma (PMH) presenting with right ventricle and pancreas involvement is very rare. Herein, we reported a 46-year-old man who presented multiple subcutaneous nodules throughout the body for eight months.Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) revealed multiplehypermetabolic lesions including in the soft tissues, right ventricle and pancreas. Fine needle aspiration of subcutaneous nodule revealed a PMH.Peritoneal lymphomatosis (PL) is a rare extranodal involvement of non-Hodgkin's lymphoma (NHL) and is associated with a poor prognosis. It is confused with the more common peritoneal carcinomatosis and may be misdiagnosed. Early diagnosis is the most important step of effective treatment. In patients with NHL, fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) is a valuable imaging modality in guiding biopsy, determining extent of the disease, and evaluating metabolic response to therapy. It also provides important information in the differential diagnosis. We report a case of a 40-year-old male patient who presented with abdominal distention and pain, with diffuse thickening of the peritoneum suggestive of peritoneal carcinomatosis on a computed tomography scan. Biopsy from the thickened peritoneum confirmed the diagnosis of diffuse large B cell lymphoma (DLBCL). Fluorine-18-FDG PET/CT performed for staging showed thickening and increased 18F-FDG uptake in almost the entire peritoneum as well as lymph node involvement in supra- and infra-diaphragmatic areas, and a mass in the spleen. Post-treatment 18F-FDG PET/CT revealed a complete metabolic response.
We performed a systematic review and meta-analysis to evaluate the application value of fluorine-18-prostate specific membrane antigen (
F-PSMA-1007) positron emission tomography/computed tomography (PET/CT) in patients with different serum prostate specific antigen (PSA) levels and primary prostate cancer (PCa) or the biochemical recurrence of PCa.

A comprehensive electronic literature search of the PubMed, Embase and Cochrane Library databases was conducted in accordance with the PRISMA statement. We calculated the pooled sensitivity and specificity of
F-PSMA-1007 PET/CT in PCa. A summary receiver operator characteristic (SROC) curve and the area under the curve (AUC) were used to assess the accuracy of
F-PSMA-1007 PET/CT for PCa.

The final analysis included 11 studies that described 799 patients and 4261 lesions with
F-PSMA-1007 PET/CT in PCa. The pooled sensitivity and specificity of
F-PSMA-1007 PET/CT in PCa were 0.836 and 0.946, respectively. The per-patient pooled sensitivity and specificity of
F-PSMA-1007 PET/CT in PCa were 0.934 and 0.453, and the per-lesion values were 0.816 and 0.979, respectively. The pooled sensitivity and specificity of
F-PSMA-1007 PET/CT in PCa with PSA>2ng/mL were 0.923 and 0.442 in a patient-based analysis and 0.799 and 0.961 in a lesion-based analysis, respectively. The pooled sensitivity and specificity of
F-PSMA-1007 PET/CT in PCa with PSA≤2ng/mL were 0.832 and 0.277 in a patient-based analysis, respectively.

This meta-analysis showed that
F-PSMA-1007 PET/CT has a higher diagnostic value for prostate cancer in the setting of primary PCa and biochemical recurrence. As serum PSA levels increase, the diagnostic accuracy of
F-PSMA-1007 PET/CT also improves.
This meta-analysis showed that 18F-PSMA-1007 PET/CT has a higher diagnostic value for prostate cancer in the setting of primary PCa and biochemical recurrence. As serum PSA levels increase, the diagnostic accuracy of 18F-PSMA-1007 PET/CT also improves.Prostate cancer (PCa) is one of the most common malignancies and cause of cancer death in men. Prostate-specific antigen (PSA) is the most used biomarker in the detection of early PCa. Lately, scientists have been using prostate-specific membrane antigen (PSMA), a glycol-protein that is over-expressed in PCa cells in positron emission tomography/ computed tomography (PET/CT) scans to detect PCa. Gallium-68-PSMA radiotracers, such as 68Ga-PSMA-11, 68Ga-PSMA-617 and 68Ga-PSMA I&T, were firstly introduced in 2011 and fluorine-18-PSMA based radiotracers followed with 18F-PSMA-1007,N-[N-[(S)-1,3-dicarboxypropyl]carbamoyl]- 4-18F-fluorobenzyl-L-cysteine(18F-DCFBC) and 2-(3-(1-carboxy-5-[(6-[18F]fluoro-pyridine-3-carbonyl)-amino]-pentyl)-ureido)- pentanedioic acid (18F-DCFPyL), also known as PYLARIFY, being the most used and showed superior results compared to conventional imaging techniques. Differences depending on half-life, clearance and normal organ uptake are being detected through research to determine which of the radiotracers, is the most suitable for each patient. Two of them, 68Ga-PSMA-11 and PLYRIFY, have already been approved by the Food and Drug Administration (FDA). The future of hybrid imaging for PCa is very promising if we consider the advantages of PSMA radiotracers compared to non-PSMA radioligands.
We aimed to examine if single photon emission computed tomography (SPECT) can discriminate between variants of frontotemporal dementia (FTD). As a secondary investigation we identify and establish the linguistic differences between those variants.

Nine patients with semantic variant primary progressive aphasia (svPPA), 8 with non-fluent variant primary progressive aphasia (nfvPPA) and 17 with behavioral variant of frontotemporal dementia (bvFTD) were compared on Addenbrooke's cognitive examination-revised (ACE-R), auditory comprehension, oral expression and verbal fluency. All patients were also compared with healthy controls. Patients were evaluated using technetium-99m-hexamethylproyleneamine oxime (
Tc-HMPAO) brain SPECT as a measure of regional cerebral flow.

Significant group differences between all patients and controls were found for ACE-R, auditory comprehension and oral expression. Semantic variant primary progressive aphasia patients performed higher in letter compared to category fluency wited that bvFTD patients share similar language deficits with svPPA patients.
Our findings suggest that SPECT may assist in the discrimination of the FTD variants. We also confirmed that bvFTD patients share similar language deficits with svPPA patients.
To investigate the correlation among the maximum standardized uptake value (SUVmax) on fluorine-18-fluorodeoxyglucose (
F-FDG) positron emission tomography/computed tomography (PET/CT) and tumor differentiation, size, and Ki67 in patients with moderately and poorly differentiate dintrahepatic cholangiocarcinoma (ICC).

The
F-FDG PET/CT imaging data of 116 patients with single ICC lesions confirmed by pathology were retrospectively evaluated. Pathological characteristics of the tumor such as the largest tumor diameter, differentiation, Ki67 expression, SUVmax of the primary tumor, and the tumor to normal background ratio (TNR) were recorded.

Among the 116 lesions, 45, 51, and 20 lesions were classified into the moderately differentiated, moderately-poorly, and poorly differentiated groups, respectively. There were significant differences in the SUVmax (P=0.033) and TNR (P=0.044) among the three groups. Maximum SUV was significantly correlated with differentiation (r=0.244, P=0.008). When the cases were categorized according to the tumor size (group 1, ≤3cm, n=14; group 2, >3 and ≤5 cm, n=37; group 3, >5 and ≤10 cm, n=52; group 4, >10 cm, n=13), there were significant differences in the SUVmax (P<0.001) and TNR (P<0.001) among the four groups. Maximum SUV was significantly correlated with tumor size (r=0.481, P<0.001). Among the 116 lesions, 38 lesions and 78 lesions were classified into the low Ki67 and high Ki67 expression groups, respectively. There were significant differences in the SUVmax (P=0.028) and TNR (P=0.007) between the two groups. Maximum SUV was significantly correlated with Ki67 expression (r=0.242, P=0.009).

In moderately and poorly differentiated ICC, the SUVmax and TNR are significantly associated with tumor differentiation, size, and Ki67 expression.
In moderately and poorly differentiated ICC, the SUVmax and TNR are significantly associated with tumor differentiation, size, and Ki67 expression.
With the recent improvements in the quantitative accuracy of single-photon emission computed tomography (SPECT)/ computed tomography (CT), the value of using standardized uptake value (SUV) in bone SPECT/CT for quantitative assessment has been reported.We established a threshold for inflamed and normal areas of the sternoclavicular joint and examined the clinical value of bone SPECT/CT.

The threshold between the inflamed and normal areas of the sternoclavicular joint was initially calculated. The diagnostic performance of the calculated threshold was subsequently compared with the visual assessment of the whole-body image. The clinical value of the threshold was examined in cases of ambiguous visual assessment and a sub-analysis with pustuloticarthro-osteitis (PAO) patients was done.

The threshold between the inflamed and the normal area in the 93 sternoclavicular joints of 51 patients was 4.46. The area under the ROC curve (AUC), accuracy, sensitivity, and specificity of SUVmax for differentiating ster initiation of treatment, especially in PAO patients.
To analyze the incidence and associated factors of hypothyroidism after radioiodine treatment for hyperthyroidism during a 13-year follow-up period.

This was a retrospective study of consecutive patients with hyperthyroidism who were treated using a single dose of radioactive iodine (RAI) with a calculated dose regimen from 07/2005 to 12/2012. Univariate and multivariate Cox regression models were used to examine the factors that are associated with the occurrence of hypothyroidism after RAI therapy. Kaplan-Meier analysis was used for confirming associations between these models.

A total of 182 patients were included during a 7.5-year median follow-up (range 6-13 years). They were 36.4±11.1 years. The mean radioactive iodine dosage was 308.2±104.3 (range 129.5-740.0) MBq. The rates of euthyroidism, early hypothyroidism, improvement, and ineffective treatment at 6 months were 48.4%, 37.9%, 8.8%, and 4.9%, respectively. The cumulative incidence of hypothyroidism in all patients with hyperthyroidism was 45.
