Abstract
Purpose: To evaluate the short-term safety and long-term efficacy of thoracoscopic surgery for esophageal atresia(EA) in low birth weight infants. Methods: From January 2011 to December 2019,a retrospective analysis on clinical data of 48 cases of low birth weight infants of EA. The clinical data were divided according to surgical methods: Thoracoscopy group A and thoracotomy group B. Variables of intra-operation, postoperative complications and mid-term postoperative complications were compared between the two groups.Results: 3 were discharged due to treatment abandoning. there were 17 cases in thoracoscopy group A and 28 cases in thoracotomy group B. The operation time of group A(172.41±20.00min)was longer than B(149.82±13.91min),the difference was statistically significant (P<0.05).the intraoperative blood loss of group A(7.41±2.83ml) was less than B(18.61±3.60ml),the difference was statistically significant (P<0.05).postoperative mechanical ventilation time, thoracic drainage time, hospital stay were not significantly different between the two groups. the incidence of anastomotic stenosis in group B(58.82%) was higher than in A(28.57%),the difference was statistically significant (P=0.045).There was no significant difference in the incidence of esophageal anastomotic fistula and recurrent tracheoesophageal fistula. After 3 years of follow-up, the incidence of thoracic deformity in group B(25%) was higher than in A(0%).The difference was significant(P=0.034).However, no significant difference was observed among the gastroesophageal reflux, symptomatic stenosis, tracheomalacia. Conclusion: Compared with thoracotomy, thoracoscopy in low weight infants with EA has the advantages of smaller incision, fewer intraoperative bleeding, and less incidence of thoracic deformities. Thoracoscopy might be a feasible surgical option for low weight infants when performed by a surgeon who has rich experience. The major mid-term complications after surgery are esophageal stenosis, gastroesophageal reflux and tracheomalacia.

Abstract
Purpose: This study aimed to investigate the effects of 3D-printed Bolus or conventional Bolus on the dosimetric distribution of target area, dose of organs at risk (OARs) and body surface dose in patients with radiotherapy after radical breast cancer surgery.Methods: 1. A 3D-printed Bolus was made on the basis of the 3D scan data of the body surface contour of the human body model used for radiation simulation. Conventional Bolus and 3D-printed Bolus were used to cover the phantom; computed tomography (CT) simulation, target area and OARs were delineated and an intensity-modulated radiotherapy (IMRT) plan was created. The conformity, uniformity and dose of the OARs were evaluated for comparative analysis. 2. Two patients undergoing radiotherapy after radical mastectomy at the Liaoning Cancer Hospital were selected to produce 3D-printed Bolus on the basis of the 3D scan data of the patient’s body surface. During radiotherapy, the conventional Bolus and 3D-printed Bolus were used for tissue compensation and a radiochromic film was used to measure the optical density (OD) values of the patient’s body surface. The difference in body surface dose between the conventional Bolus and the 3D-printed Bolus was analysed.Results: 1. The conformal index (CI) , heterogeneity index (HI) and dose of OARs of the 3D-printed Bolus intensity-modulated radiation therapy plan of the human body model used for radiation simulation were all superior to those of the conventional Bolus (CI = 0.941 vs. 0.979, HI = 0.134 vs. 0.288). 2. In the two patients undergoing radiotherapy after radical mastectomy for breast cancer, the OD values of the radiation chromogenic film using 3D-printed Bolus radiotherapy were higher than those using conventional Bolus (patient 1: P = 0.047; patient 2: P = 0.016).Conclusions: Compared with conventional Bolus, 3D-printed Bolus has obvious advantages in the target dose distribution of radiotherapy after radical breast cancer surgery and protection of OARs. Thus, it could improve the body surface dose of patients and should be promoted and applied in clinical treatment.

Abstract
Purpose: This longitudinal study aims to evaluate the performance of 68 Ga-FAPI-04 and 18 F-FDG and to profile the dynamic process of tumor metastasis in a preclinical 4T1 breast cancer model. Although both of these two radioligands are wildly used in clinic, no study was reported on their performance in the longitudinal monitoring of tumor metastasis. Also, no correlation between the expression level of fibroblast activation protein (FAP) and the development of tumor metastasis has been elucidated previously. In this study, we evaluated the performance of 68 Ga-FAPI-04 and 18 F-FDG PET during the entire process of tumor metastasis, and their potential for the early diagnosis of tumor metastasis. We also clarified the correlation of uptakes as well as the signal-to-background (S/B) ratios between these two probes at different stages of tumor metastasis. Methods: Forty 4T1 metastatic breast cancer murine model were established using female BALB/c mice, followed by the longitudinal imaging with 68 Ga-FAPI-04 and 18 F-FDG once a week for up to six weeks. In vitro Hematoxylin & Eosin (H&E) and immunochemistry (IHE) staining were performed to evaluate FAP expression on the metastatic lesions. Further statistical analysis was performed to evaluate the correlation of 68 Ga-FAPI-04 and 18 F-FDG uptake (%ID/cc) at different stages of the metastasis. Results: 68 Ga-FPAI-04 holds an advantage over 18 F-FDG with higher sensitivity at the early stage of tumor metastasis. However, with the progress of tumor metastasis, uptake of 68 Ga-FAPI-04 decreases and becomes less sensitive than 18 F-FDG. There is also no direct correlation between uptake or S/B ratios of 68 Ga-FAPI-04 and 18 F-FDG during this dynamic process. Conclusion: 68 Ga-FAPI-04 is more sensitive than 18 F-FDG in detecting the early stage of tumor metastasis, but becomes less sensitive than 18 F-FDG at the late stage of tumor metastasis. We envision this result would be meaningful for the explanation of the 18 Ga-FAPI-04 and 18 F-FDG imaging both in the future clinic and preclinic studies.

Abstract

Prionchulus jonkershoekensis n. sp. is described from South Africa and illustrated using morphological, morphometric, and molecular techniques. This species is characterized by its body length (1.78–2.14 mm); the size of buccal cavity (38–44 × 24–31 µm), lower dorsal tooth position in relation to buccal cavity base, the position of amphidial aperture just above dorsal tooth apex, pars proximalis vaginae with almost straight walls, and tail 144–158 µm long with sickle shaped posterior third part. Phylogenetic analyses based on 18 S rDNA and 28 S rDNA of P. jonkershoekensis n. sp. revealed close relationships of the new species with Prionchulus punctatus and Prionchulus muscorum. This is also an additional geographical record for the genus from South Africa.

Abstract
The environmental release of mercury is continuously increasing with high degree of mobility, transformation and amplified toxicity. Improving remediation strategies is becoming increasingly important to achieve more stringent environmental safety standards. This study develops a laboratory-scale reactor for bioremediation of aqueous mercury using a biofilm-producing bacterial strain, KBH10, isolated from mercury-polluted soil. The strain was found resistant to 80 mg/L of HgCl2 and identified as Bacillus nealsonii via 16S rRNA gene sequence analysis. The strain KBH10 was characterized for optimum growth parameters and its mercury biotransformation potential was validated through mercuric reductase assay. A packed-bed column bioreactor was designed for biofilm-mediated mercury removal from artificially contaminated water and residual mercury was estimated. Strain KBH10 could grow at a range of temperature (20–50 °C) and pH (6.0–9.0) with optimum temperature established at 30 °C and pH 7.0. The optimum mercuric reductase activity (77.8 ± 1.7 U/mg) was reported at 30 °C and was stable at a temperature range of 20–50 °C. The residual mercury analysis of artificially contaminated water indicated 60.6 ± 1.5% reduction in mercury content within 5 h of exposure. This regenerative process of biofilm-mediated mercury removal in a packed-bed column bioreactor can provide new insight into its potential use in mercury bioremediation.

Published: March 2021

Background
Anxiety symptoms in older adults are prevalent and disabling but often go untreated. Most trials on psychological interventions for anxiety in later life have examined the effectiveness of face-to-face cognitive behavioral therapy (CBT). To bridge the current treatment gap, other treatment approaches and delivery formats should also be evaluated.

Objective
This study is the first to examine the effectiveness of a brief blended acceptance and commitment therapy (ACT) intervention for older adults with anxiety symptoms, compared with a face-to-face CBT intervention.

Methods
Adults aged between 55-75 years (n=314) with mild to moderately severe anxiety symptoms were recruited from general practices and cluster randomized to either blended ACT or face-to-face CBT. Assessments were performed at baseline (T0), posttreatment (T1), and at 6- and 12-month follow-ups (T2 and T3, respectively). The primary outcome was anxiety symptom severity (Generalized Anxiety Disorder-7). Secondary outcomes were positive mental health, depression symptom severity, functional impairment, presence of Diagnostic and Statistical Manual of Mental Disorders V anxiety disorders, and treatment satisfaction.

Results
Conditions did not differ significantly regarding changes in anxiety symptom severity during the study period (T0-T1: B=.18, P=.73; T1-T2: B=−.63, P=.26; T1-T3: B=−.33, P=.59). Large reductions in anxiety symptom severity (Cohen d≥0.96) were found in both conditions post treatment, and these were maintained at the 12-month follow-up. The rates of clinically significant changes in anxiety symptoms were also not different for the blended ACT group and CBT group (χ21=0.2, P=.68). Regarding secondary outcomes, long-term effects on positive mental health were significantly stronger in the blended ACT group (B=.27, P=.03, Cohen d=0.29), and treatment satisfaction was significantly higher for blended ACT than CBT (B=3.19, P<.001, Cohen d=0.78). No other differences between the conditions were observed in the secondary outcomes.

Conclusions
The results show that blended ACT is a valuable treatment alternative to CBT for anxiety in later life.

Published: March 2021

Objective: The study was carried out to identify measures for preventing conflicts between farmers and cattle herdsmen in rural communities of Benue State, Nigeria. The specific objectives were to: Describe the socioeconomic characteristics of the respondents; ascertain the causes of conflict between farmers and cattle herdsmen in the study area; and identify measures required for preventing conflicts between farmers and cattle herdsmen.
Methods: Data were collected from a sample of one hundred and eighteen (118) respondents in four communities in the study area using a well-structured questionnaire. Descriptive statistics such as frequency, percentage, mean, and standard deviation were used for data analysis.
Results: Majority (90.7%) of the respondents had farming as a major source of livelihood, 55.1% were male while 62.7% were married. Damage to crops by cattle (x̄=2.72), uncontrolled grazing (x̄=2.52), herders claiming the land as common property (x̄=2.40), and destruction of farmland (x̄=2.30) were the major causes of conflicts. Measures required for preventing conflicts between farmers and cattle herdsmen include herdsmen education on the effects of the conflict (x̄=2.21), signing of a peace accord by both parties (x̄=2.12), establishment of ranches (x̄=2.06), implementation of law prohibiting open grazing (x̄=2.05), and disarming both parties (x̄=1.87).
Conclusion: Educating farmers and herdsmen on the effects of the conflict, signing of a peace accord agreement by both parties, establishment of ranches, implementation of law prohibiting open grazing, and disarming both parties were measures required for preventing conflicts between farmers and cattle herdsmen. It is recommended that law enforcement agencies should enforce law on open grazing to avoid conflicts between farmers and cattle herdsmen in the area.

Authors: Salahshour Mohammad Ali , Ashrafi Ali Reza 
Published: March 2021

A group $H$ is said to be capable, if there exists another group$G$ such that $\frac{G}{Z(G)}~\cong~H$, where $Z(G)$ denotes thecenter of $G$. In a recent paper \cite{2}, the authorsconsidered the problem of capability of five non-abelian $p-$groups of order $p^4$ into account. In this paper, we continue this paper by considering three other groups of order $p^4$. It is proved that the group $$H_6=\langle x, y, z \mid x^{p^2}=y^p=z^p= 1, yx=x^{p+1}y, zx=xyz, yz=zy\rangle$$ is not capable. Moreover, if $p > 3$ is prime and $d \not\equiv 0, 1 \ (mod \ p)$ then the following groups are not capable:\\{\tiny $H_7^1=\langle x, y, z \mid x^{9} = y^3 = 1, z^3 = x^{3}, yx = x^{4}y, zx = xyz, zy = yz \rangle$,\\$H_7^2= \langle x, y, z \mid x^{p^2} = y^p = z^p = 1, yx = x^{p+1}y, zx = x^{p+1}yz, zy = x^pyz \rangle,$ \\$H_8^1=\langle x, y, z \mid x^{9} = y^3 = 1, z^3 = x^{-3}, yx = x^{4}y, zx = xyz, zy = yz \rangle$,\\$H_8^2=\langle x, y, z \mid x^{p^2} = y^p = z^p = 1, yx = x^{p+1}y, zx = x^{dp+1}yz, zy = x^{dp}yz \rangle$.}
ON THE ROOTS OF TOTAL DOMINATION POLYNOMIAL OF GRAPHS, II
Authors: Alikhani Saeid , Jafari Nasrin 
Published: March 2021

Let $G = (V, E)$ be a simple graph of order $n$. A total dominating set of $G$ is a subset $D$ of $V$, such that every vertex of $V$ is adjacent to at least one vertex in $D$. The total domination number of $G$ is minimum cardinality of total dominating set in $G$ and is denoted by $\gamma_t(G)$. The total domination polynomial of $G$ is the polynomial $D_t(G,x)=\sum_{i=\gamma_t(G)}^n d_t(G,i)$, where $d_t(G,i)$ is the number of total dominating sets of $G$ of size $i$. In this paper, we study roots of the total domination polynomial of some graphs. We show that all roots of $D_t(G, x)$ lie in the circle with center $(-1, 0)$ and radius $\sqrt[\delta]{2^n-1}$, where $\delta$ is the minimum degree of $G$. As a consequence, we prove that if $\delta\geq \frac{2n}{3}$, then every integer root of $D_t(G, x)$ lies in the set $\{-3,-2,-1,0\}$.
