Published: February 2021

Purpose:
Laparoscopic rectal surgery has moved from being experimental to getting established as a mainstream procedure. We aimed at analysing how rectal cancer surgery has evolved at our institute.

Methods:
A retrospective review of 1000 consecutive patients who underwent laparoscopic anterior resection for rectal adenocarcinoma over a period of 15 years (January 2005 to December 2019) was performed. Technical modifications were made with splenic flexure mobilisation, intersphincteric dissection and anastomotic technique. The data collected included type of surgery, duration of surgery, conversion to open, anastomotic leak, defunctioning stoma and duration of hospital stay. The first 500 and the next 500 cases were compared.

Results:
The study patients were predominantly males comprising 68% (n = 680). The mean age of the patients was 58.3 years (range: 28–92 years). Majority of the procedures performed were high anterior resection (n = 402) and low anterior resection (LAR) (n = 341) followed by ultra-LAR (ULAR) (n = 208) and ULAR + colo-anal anastomosis (n = 49). A total of 42 patients who were planned for laparoscopic surgery needed conversion to open procedure. Forty-one patients (4.1%) had an anastomotic leak. The mean duration of stay was 5.3 + 2.8 days. The rate of conversion to open procedure had reduced from 5.4% to 3.0%. The rate of defunctioning stoma had reduced by >50% in the recent group. The anastomotic leak rate had reduced from 5.0% to 3.2%. The average duration of stay had reduced from 5.8 days to 4.9 days.

Conclusion:
This is one of the largest single-centre experiences of laparoscopic anterior resection. We have shown the progressive benefits of an evolving approach to laparoscopic anterior resection.

Published: February 2021

Background:
In retro-gastric Pancreatic pseudocyst (PP) Laparoscopic cystogastrostomy (LCG) is an established procedure of drainage.

Aims and Objectives:
To compare surgical outcome between laparoscopic cysto-gastrostomy conventional method and plication of the edge of anterior gastrotomy in patients of pancreatic pseudocyst.

Materials and Methods:
Twenty six patients were underwent LCG from 2010-2020 by a single surgeon. Both the conventional LCG group Group-1(Gr-1) and the plication group Group-2 (Gr-2) where plication of edge of anterior gastrostomy was performed, contained 13 patients each.

Results:
The numbers of male/female in Gr-1 was 9/4 and that in Gr-2 was 10/3 (P = 1). Mean ages of patients were 45.3 ± 10.4 years (range 23-60) in Gr-1 and 48.0 ± 12.3 years (range 27-65) in Gr-2. Etiological factors were alcohol (46.1% in Gr-1, 53.8% in Gr-2), gallstone disease (38.4% in Gr-1,15.3% in Gr-2), trauma (15.3% in each groups), idiopathic cause (15.3% in Gr-2). The cyst size was 9.0 ± 1.5 cm in Gr-1and 8.9 ± 2.1cm in Gr-2. The mean operative time in Gr-1 (107.6 ± 12.5 minutes) was longer than Gr-2 (97 ± 1 3.6 minutes) (P = 0.06). The size of cystogastric anastomosis in Gr-1 was 4.6 ± 0.7 cm and that in Gr-2 was 4 ± 0.8 cm (P = 0.04). The intra-operative blood loss in Gr-1 and Gr-2 were 101.9 ± 21.7ml and 78.4 ± 30.7 ml respectively. There was a significant change in intraoperative blood loss and stoma size in Gr-2. The postoperative complications were managed conservatively. No recurrence over a period of 18 months of follow-up.

Conclusion:
Plication of edges of anterior gastrostomy result in reduction in operative time, smaller anastomosis without complication and less intra-operative blood loss.

Authors: Wang Yu-Dan , Qin Jia-An , Wu Liu , Wang Bao-Min , Eremin Sergei , Yang Shi-Hai , Yang Mei-Hua 
Published: February 2021

Objectives:
An enzyme-linked immunosorbent assay (ELISA) and colloidal gold-based immunochromatographic (ICG) strip assay will be developed for the rapid and high-throughput detection of atrazine (ATZ) in medicinal herbs.

Methods:
A monoclonal antibody against ATZ was obtained after the immunization of mice, cell fusion, and hybridoma screening, and the antibody was used to develop direct competitive ELISA (dcELISA) and the ICG strip assay.

Results:
Both dcELISA and ICG strip methods were established, optimized, and validated for the detection of ATZ in Salviae miltiorrhizae radix et rhizome, Astragali radix, and Isatidis radix. dcELISA had a half-maximum inhibition concentration of 10.56 ng/mL (Salviae miltiorrhizae radix et rhizome), 7.6 ng/mL (Astragali radix), and 8.15 ng/mL (Isatidis radix). The limit of detection (LOD) of the ICG strip assay was 12.5 ng/mL (Salviae miltiorrhizae radix et rhizome), 12.5 ng/mL (Astragali radix), and 6.25 ng/mL (Isatidis radix) in different herb matrices. Due to the recognition characteristics of the monoclonal antibody for the pesticides ATZ, propazine, sebuthylazine, and prometryn, the detection results of real samples by the two immunoassays were confirmed by liquid chromatography–tandem mass spectrometry, which proved the accuracy and reliability of the established methods.

Conclusion:
The proposed dcELISA and ICG strip methods were suitable for the rapid, convenient, and high-throughput detection of ATZ in these medicinal herbs.

Published: February 2021

Objective:
Belamcandae Rhizoma and Iridis Tectori Rhizoma are easily confused with each other. The main objective of this study is to distinguish them using chemical analysis.

Materials and Methods:
Thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC) fingerprint methods were established to compare the chemical profile, while HPLC quantitation was used to determine the contents of three isoflavones in thirty batches of Belamcandae Rhizoma and Iridis Tectori Rhizoma samples.

Results:
The two herbs could be distinguished by TLC using acetic acid-n hexane-ethyl acetate (1:90:80 v/v/v) as the mobile phase, according to the fluorescent band under 366 nm at R
f 0.2. In total, 12 compounds were identified in the 24-min HPLC fingerprint. The similarity coefficient between the two herbs was 0.54 ± 0.01. Mangiferin (1), tectoridin (2), iridin (3), irigenin (5), irisflorentin (6), and iristectorin A (9) were the main peaks in Belamcandae Rhizoma, while tectoridin (2) and tectorigenin (4) were the major peaks in Iridis Tectori Rhizoma. The contents of 2 in Iridis Tectori Rhizoma (2.50 ± 0.20 %) were 8.93 times higher than that of Belamcandae Rhizoma (0.28 ± 0.08 %), while the ones of 5 and 6 were slightly lower in Iridis Tectori Rhizoma.

Conclusions:
The study established fast and effective methods to distinguish Belamcandae Rhizoma from Iridis Tectori Rhizoma.

Published: February 2021

Objective:
Authentication is vital to the reduction of the misuse of Panax species due to their extensive array of uses and similarities between species. However, the current authentication approach is time-consuming, laborious, and costly. The aim of this study is to discriminate the botanical origins of five species in Panax genus by a rapid and simple approach.

Methods:
Here, an electronic tongue (E-tongue) was applied to discriminate the botanical origins of five species of Panax, i.e., Panax quinquefolius, Panax japonicus, P. japonicus var. major, Panax zingiberensis, and Panax notoginseng (representative high-, middle-, and low-latitude plants), and the four geographical origins of P. japonicus and P. japonicus var. major plants. Data preprocessing methods, including principal component analysis (PCA), hierarchical cluster analysis (HCA), and linear discriminant analysis (LDA), were used.

Results:
Three models can discriminate five species of Panax genus and four plants of P. japonicus and P. japonicus var. major from different geographical origins. LDA was superior to PCA and HCA in terms of satisfactory classification.

Conclusion:
The findings confirmed the potential of the E-tongue for performing rapid, simple, and cost-effective discrimination via LDA.
Palynostratigraphic and palynofacies analysis of x and y wells, offshore Niger Delta, Nigeria
Authors: Fadiya S.L. , Ogunleye S.O. , Oyelami A.B. , Aroyewun F.R. 
Published: February 2021

A detailed palynostratigraphic and palynofacies study was carried out on two shallow offshore wells, codenamed Well X and Well Y, from the Niger Delta Basin, Nigeria. The study is aimed at establishing the age and palaeoenvironment of the sedimentary sequences penetrated by the wells. Standard palynological/palynofacies laboratory procedures were used to free the palynomorphs and palynomacerals from the embedding matrices.Prepared palynological slides were studied using the Leitz Ortholux II transmitted light microscope. The palynofloral assemblages recorded from the two well sequences include well-preserved palynomorphs such as Zonocostites ramonae, Monoporites annulatus, Retitricolporites irregularis, Cyperaceaepollis sp., Echitricolporites spinosus and Nymphaeapollis clarus among others. The recognition of diagnostic pollen of Cyperaceaepollis sp. and Nymphaeapollis clarus as well as the associated palynomorph assemblage aided the delineation of the well sequences into the P830, P840-P850 and P860 subzones of the P800 palynological zone in the late Miocene. The relative abundance of particulate organic matter (Amorphous Organic Matter (AOM), Phytoclasts and Palynomorphs) revealed the delineation of three palynofacies assemblages, PF-A, PF-B and PF-C, suggesting three distinct paleoenvironments of deposition. These paleoenvironments range from distal shelf through marginal to proximal with varying conditions from oxic, suboxic to anoxic, thus suggesting marginal marine to coastal deltaic environments of deposition for the sedimentary sequences penetrated by the two wells.
Keywords: Late Miocene, Niger Delta, Paleoenvironment, Palynostratigraphy, Palynofacies.

Published: February 2021

<p>In recent years there is an increasing interest about STEAM (Science, Technology, Engineering, Arts &amp; Mathematics) model in education. STEAM is a cross-disciplinary approach which breaks down the barriers among disciplines, offers a dynamic character in teaching and sheds light on various aspects of the aforementioned parts of STEAM equation with multiple benefits for all children including those with disabilities. Furthermore, the increasing interest and the development of museum educational programs for school groups provide unique opportunities in STEAM education that are not available in schools. The museum as nonformal learning environment and its exhibits, the qualitative characteristics of learning and the wide range of the expected learning outcomes enrich the design and implementation of STEAM educational programs providing meaningful learning experiences for all children. The present paper refers to a cross-disciplinary approach which connects STEAM education, Museum Education and Special Education for the design and implementation of an educational program for a school group of children with disabilities. The educational program “Making mosaics with bricks and colors” was based on a. the STEAM approach, b. the characteristics of learning in the museum, c. the principles of Differentiated Instruction (DI) and Universal Design for Learning (UDL), and d. the unique characteristics of a thematic technological museum for the industrial heritage in Greece where the educational program took place. Based on the experience of the implementation of the educational program and the qualitative data of the evaluation of the program, it is argued that STEAM education as well as collaborations between different specialists and between schools and museums provides meaningful learning experiences to all children including those with disabilities.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0653/a.php" alt="Hit counter" /></p>

Authors: De Oliveira Ricardo Santos 
Published: February 2021

On 11 March, the WHO confirmed coronavirus disease 2019 as a pandemic. The Director-General of the WHO called on governments to change its course by taking "urgent and aggressive action" (1). In terms of the number of deaths COVID-19 has caused 1.919.126 deaths, reported to WHO as of January 10, 2021. (https://covid19.who.int).
The COVID-19 pandemic has posed unprecedent challenges to healthcare worldwide, including neurosurgical units. Medical workers, pediatric neurosurgeons included, should be aware of safety measures and follow the recommendations of local healthcare organizations to prevent and control the disease (2).
During the year 2020 the scientific community worked tirelessly in search of a solution to stop the COVID-19. Several scientific studies have been published analyzing the effects of different drugs on the stages of COVID-19. However, in an unprecedented way in history independent groups have produced different options for vaccines against coronavirus (3).
The vaccination rollout comes with a mixed bag of emotions and hope. We cannot celebrate yet, but it is certainly a relief to start the year 2021 with the hope of COVID-19 control. A terrible disease that has been
producing lethal effects and sequelae in different peoples around the world.
COVID-19 has exposed vulnerabilities, magnified weaknesses, and exacerbated long-festering issues. We will continue to believe in science and overcome this terrible obstacle in our lives.
It’s the light at the end of the tunnel. We’re not there yet, but it’s a big relief to know there can be an end to this pandemic.
