The large number of old, damaged, or dead tea plants cause the plant population per hectare to be low that eventually decreases the productivity. Propagation using the transplantation technique is used for embroidery because it has the advantage of a shorter immature plant period and higher seed size so that it can compensate for the surrounding plants but the weakness of transplantation is low success rate. This study aims to 1) determine the morphological changes of root transplantation and biochemistry on TRI 2025 clone transplantation using cocopeat, husk charcoal, and moss, 2) determine the success rate of transplantation in each medium. This research was conducted in August 2018–January 2019 at the Pagilaran production garden, PT. Pagilaran, Batang, Central Java. Field experiments were prepared using a single factor Completely Randomized Environment Design (CRD). The factors tested were the type of transplantation media, namely the media of husk charcoal, cocopeat, and moss. Observations were made on transplantation root morphology, levels of glucose, sucrose, and total sugar in the transplanted stem bark and the concentration of auxin, gibberellin, and cytokinin in the transplant roots. The data obtained were then analyzed using variance and if there was a significant difference between treatments, the Duncan multiple distance test (DMRT) was continued at the 95% confidence level. The results showed that the type of media had no significant effect on the ability to form glucose, sucrose, and total sugar in the bark. The development of root morphology of cocopeat media was seen to be the highest. The ratio of cytokinin/auxin in cocopeat was the lowest but the highest levels of cytokinin and auxin were found in moss, while cocopeat had the highest level of gibberellin. The highest transplanting success rate was found in moss medium with 58.33%, cocopeat and husk charcoal media had the same success rate, namely 41.60%.   Keywords: transplantation, biochemistry, media, success, TRI 2025

The research aimed to propagate tea plants by air layering in order to obtain new plants with shorter immature plants period (TBM), which is 1.5 years, by utilizing wasted branches from routine clean pruning activities in tea plantations. The research was conducted from August 2018 to January 2019 at tea plantation of PT. Pagilaran, Batang, Central Java. Experiment using single factor treatment was arranged in a Completely Randomized Design with three replications. The treatment was layering media, consisting of husk charcoal, moss, and cocopeat, which were applied on GMB 7 and GMB 9 clones. The results showed significant effects of the layering media on the levels of auxin and cytokinin in GMB 7. The highest levels were found in the husk charcoal and moss media. Analysis of sucrose, glucose and total sugar as well as the physiological analysis of the air layering roots showed no significant difference in the fresh weight, dry weight, volume, surface area, diameter, and length of the roots. Husk charcoal resulted in the highest success rate of the air layering in GMB 7, which was 100%. Meanwhile, GMB 9 showed significant difference only in the auxin levels. There was no significant effect of layering media on the analysis of sucrose, glucose and total sugar as well as on the physiological analysis of the air layering roots. Both husk charcoal and moss media resulted in the highest success rate of the air layering in GMB 9, which was 58.33%.

Objective: To compare the success rate of different obturation procedures in primary mandibular second molars clinically and also by digital radiovisiography. Methods: A total of 40 children aged between 4-8 years with deeply carious mandibular second primary molars indicated for single session pulpectomy were selected. Canals were obturated with Metapex. The 3 study groups (Endodontic plugger, Handheld lentulospiral, Navi Tip syringe) were compared with the control group (reamer) both clinically and radiovisiographically. The data collected were statistically analyzed using Pearson’s Chi-square and Fisher’s exact test. Results: The use of Navi tip syringe led to the least number of voids followed by Endodontic plugger and Reamer and the highest number of voids was reported with Lentulospiral. Navitip presented maximum number of optimally filled cases followed by Endodontic plugger and Lentulospiral and least number of optimally filled cases with reamer. However, there was no statistically significant difference (p>0.05) in any of the groups with clinical (pain and tenderness to percussion) and radiographic parameters (presence or absence of voids and length of obturation). Conclusion: Within the limitations of the present study, though the clinical outcome was statistically insignificant, Navitip syringe exhibited encouraging results and is a promising option for obturation in primary teeth.

Background: Morphological changes characteristic of femoroacetabular impingement (FAI) are common in soccer players. However, the clinical relevance of such anatomical variations is still not well-defined. Hypothesis: We hypothesized that high alpha angle values and/or acetabular retroversion index (ARI) are correlated with rotational range of motion (ROM) of the hip and that there are clinical-radiological diferences between the dominant lower limb (DLL) and nondominant lower limb (NDLL) in professional soccer players. Study Design: Cross-sectional. Level of Evidence: Level 3. Methods: A total of 59 male professional soccer players (average age 25.5 years, range 18-38 years) were evaluated in the preseason. As main outcome measures, we evaluated the alpha angle and the ARI and hip IR and ER ROM with radiographic analysis. Results: The measurements taken on DLL and NDLL were compared and a significant difference was found between the sides in the ER ( P = 0.027), where the DLL measures were 1.54° (95% CI, 0.18-2.89) greater than the NDLL. There were no significant differences between the sides in the measures of IR ( P > 0.99), total ROM ( P = 0.07), alpha angle ( P = 0.250), and ARI ( P = 0.079). The correlations between the rotation measurements and the alpha angle in each limb were evaluated and the coefficient values showed no correlation; so also between the ARI and rotation measures. Conclusion: Morphological changes of the femur or acetabulum are not correlated with hip IR and ER ROM in male professional soccer players. ER on the dominant side was greater than on the nondominant side. There was no significant difference in the other measurements between sides. Clinical Relevance: In clinical practice, it is common to attribute loss of hip rotational movement to the presence of FAI. This study shows that anatomical FAI may not have a very strong influence on available hip rotational movement in professional soccer athletes.

AbstractChronic pancreatitis (CP) is an end-stage disease with no specific therapy; therefore, an early diagnosis is of crucial importance. In this study, data from 1315 and 318 patients were analysed from acute pancreatitis (AP) and CP registries, respectively. The population from the AP registry was divided into AP (n = 983), recurrent AP (RAP, n = 270) and CP (n = 62) groups. The prevalence of CP in combination with AP, RAP2, RAP3, RAP4 and RAP5 + was 0%, 1%, 16%, 50% and 47%, respectively, suggesting that three or more episodes of AP is a strong risk factor for CP. Laboratory, imaging and clinical biomarkers highlighted that patients with RAP3 + do not show a significant difference between RAPs and CP. Data from CP registries showed 98% of patients had at least one AP and the average number of episodes was four. We mimicked the human RAPs in a mouse model and found that three or more episodes of AP cause early chronic-like morphological changes in the pancreas. We concluded that three or more attacks of AP with no morphological changes to the pancreas could be considered as early CP (ECP).The new diagnostic criteria for ECP allow the majority of CP patients to be diagnosed earlier. They can be used in hospitals with no additional costs in healthcare.

This study investigated the perception and learning of relative pitch using vibrotactile stimuli by musicians with and without a hearing impairment. Notes from C3 to B4 were presented to the fingertip and forefoot. Pre- and post-training tests in which 420 pairs of notes were presented randomly were carried out without any feedback to participants. After the pre-training test, 16 short training sessions were carried out over six weeks with 72 pairs of notes per session and participants told whether their answers were correct. For amateur and professional musicians with normal hearing and professional musicians with a severe or profound hearing loss, larger pitch intervals were easier to identify correctly than smaller intervals. Musicians with normal hearing had a high success rate for relative pitch discrimination as shown by pre- and post-training tests, and when using the fingertips, there was no significant difference between amateur and professional musicians. After training, median scores on the tests in which stimuli were presented to the fingertip and forefoot were >70% for intervals of 3–12 semitones. Training sessions reduced the variability in the responses of amateur and professional musicians with normal hearing and improved their overall ability. There was no significant difference between the relative pitch discrimination abilities between one and 11 semitones, as shown by the pre-training test, of professional musicians with and without a severe/profound hearing loss. These findings indicate that there is potential for vibration to be used to facilitate group musical performance and music education in schools for the deaf.

Pyelonephritis (PN) represents an important cause of morbidity in the pediatric population, especially in uropathic patients. The aim of the study is to demonstrate differences between PNs of uropathic patients and PNs acquired in community in terms of uropathogens involved and antibiotic sensitivity; moreover, to identify a proper empiric therapeutic strategy. A retrospective study was conducted on antibiograms on urine cultures from PNs in vesicoureteral reflux (VUR) patients admitted to pediatric surgery department and from PNs in not VUR patients admitted to Pediatric Emergency Unit between 2010 and 2020. We recorded 58 PNs in 33 patients affected by VUR and 112 PNs in the not VUR group. The mean age of not VUR patients at the PN episode was 1.3 ± 2.6 years (range: 20 days of life–3 years), and almost all the urine cultures, 111 (99.1%), isolated Gram-negative bacteria and rarely, 1 (0.9%), Gram-positive bacteria. The Gram-negative uropathogens isolated were Escherichia coli (97%), Proteus mirabilis (2%), and Klebsiella spp. (1%). The only Gram-positive bacteria isolated was an Enterococcus faecalis. As regards the antibiograms, 96% of not VUR PNs responded to beta-lactams, 99% to aminoglycosides, and 80% to sulfonamides. For the VUR group, mean age was 3.0 years ± 3.0 years (range: 9 days of life–11 years) and mean number of episodes per patient was 2.0 ± 1.0 (range: 1–5); 83% of PNs were by Gram-negatives bacteria vs. 17% by Gram-positive: the most important Gram-negative bacteria were Pseudomonas aeruginosa (44%), Escherichia coli (27%), and Klebsiella spp. (12%), while Enterococcus spp. determined 90% of Gram-positive UTIs. Regimen ampicillin/ceftazidime (success rate: 72.0%) was compared to ampicillin/amikacin (success rate of 83.0%): no statistically significant difference was found (p = 0.09). The pathogens of PNs in uropathic patients are different from those of community-acquired PNs, and clinicians should be aware of their peculiar antibiotic susceptibility. An empiric therapy based on the association ampicillin + ceftazidime is therefore suggested.

Objective. Ectopic pregnancy adversely affects the patency of the fallopian tube and consequently the future pregnancy. There are different options of conservative treatment of tubal pregnancy such as methotrexate and salpingostomy [1]. There is little information on the success rate of maintaining tubal patency after methotrexate and salpingostomy [2]. Therefore, the aim of this study is to evaluate the ipsilateral tubal patency using HyCoSy after treatment of tubal pregnancy with methotrexate therapy versus salpingostomy. Patients and methods. This was a case-series study conducted in Ain Shams and Al-Azhar University Maternity Hospitals to evaluate the ipsilateral tubal patency using hysterosalpingo-contrast sonography (HyC0Sy) following salpingostomy and medical treatment of tubal pregnancy. This study included patients who were admitted to Ain Shams and Al-Azhar University Maternity Hospitals for having tubal pregnancy and were treated either with methotrexate or salpingostomy over a 4-year period between January 2017 and December 2020. The patients seeking fertility were re-evaluated for fallopian tubes patency by hysterosalpingogram 3 months after discharge. The study included 2 groups of women: group I (n = 200): women who were treated with methotrexate, and group II (n = 140): women who underwent salpingostomy. Results. HSG was performed in 200 cases of patients with tubal pregnancy who were treated with methotrexate and 140 cases of patients who underwent salpingostomy. The patency of the ipsilateral tube was 85% after methotrexate treatment and 84.2% after salpingostomy. There was no statistically significant difference between the two groups. Conclusion. The findings suggest similar success rate in maintaining the patency of the fallopian tube with either methotrexate or salpingostomy. Key words: ectopic pregnancy, hysterosalpingography, methotrexate, infertility, salpingostomy

Objectives To compare the clinical outcomes of patients undergoing additional procedures in endoscopic endonasal dacryocystorhinostomy (End-DCR) surgery and discuss the factors affecting the success of End-DCR surgery in light of relevant literature. Methods The study included 155 patients who underwent End-DCR surgery in our clinic due to epiphora. This was a prospective randomized, single-blind, controlled trial. Group I (control) included 54 patients who did not undergo silicone stent insertion or silver nitrate application, group II included 51 patients who underwent silicone stent insertion only, and group III included 50 patients who underwent silver nitrate application only. Statistical analysis was performed on follow-up data regarding anatomic and functional success rates. Results Revision surgery was performed in 16 patients who developed persistent epiphora in the postoperative period, including 6 in group I, 7 in group II, and 3 in group III ( P = .4). The most common reason for revision surgery was stenosis of the neo-ostium ( n = 8), followed by granulation tissue formation ( n = 5) and synechia formation ( n = 3). Granuloma formation was the most common postoperative complication, and a significant difference was found among the groups with regard to granuloma formation ( P = .04). At postoperative month 12, the functional success rate was estimated to be 88%, 86%, and 94%, and the anatomic success rate was estimated to be 94%, 92%, and 96% in groups I, II, and III, respectively, with no significant difference, found among the 3 groups with regard to both rates ( P = .79 and P = .76, respectively). Conclusion The results indicated that stenting and silver nitrate application did not affect surgical success. Our preliminary results on silver nitrate cauterization showed that it is an effective, inexpensive, and practical method to reduce granulation formation in the postoperative period.

Objective: The aim of the present study was to investigate the effect of allergic rhinitis on the success of the operation in chronic otitis surgery by using score for allergic rhinitis (SFAR). Materials and Methods: In the present study; 121 patients, who underwent type 1 tympanoplasty were examined retrospectively. SFAR of all patients were recorded. The graft success rates of 26 patients with allergic rhinitis (AR) and 95 patients with no allergic rhinitis group (NAR) were compared. Results: While the graft success rate in NAR group was 89.5%, this rate was 80.8% in the AR group. However, the difference between groups was not statistically significant (p = 0.311). Conclusion: These findings suggest that allergic rhinitis decreases the graft success rate of the pathologies occurring in eustachian tube, middle ear and mastoid although statistically significant difference wasn’t found. Prospective studies with larger patient groups are required in order to evaluate this pathology.

Fumonisin B1 (FB1) is a common mycotoxin produced by Fusarium species particularly F. proliferatum and F. verticillioides. The toxin produced can cause adverse effects on humans and animals. The objectives of this study were to detect the production of FB1 based on the amplification of FUM1 gene, to quantify FB1 produced by the isolates using Ultra-fast Liquid Chromatography (UFLC) analysis, to examine the embryotoxicity effect of FB1 and to determine EC50 toward the larvae of zebrafish (Danio rerio). Fifty isolates of Fusarium species were isolated from different hosts throughout Malaysia. Successful amplification of the FUM1 gene showed the presence of this gene (800 bp) in the genome of 48 out of 50 isolates. The highest level of FB1 produced by F. proliferatum isolate B2433 was 6677.32 ppm meanwhile F. verticillioides isolate J1363 was 954.01 ppm. From the assessment of embryotoxicity test of FB1 on larvae of zebrafish, five concentrations of FB1 (0.43 ppm, 0.58 ppm, 0.72 ppm, 0.87 ppm and 1.00 ppm) were tested. Morphological changes of the FB1 exposed-larvae were observed at 24 to 168 hpf. The mortality rate and abnormality of zebrafish larvae were significantly increased at 144 hpf exposure. Meanwhile, the spontaneous tail coiling showed a significant difference. There were no significant differences in the heartbeat rate. As a conclusion, the presence of FUM1 in every isolate can be detected by FUM1 gene analysis and both of the species produced different concentrations of FB1. This is the first report of FB1 produced by Fusarium species gave a significant effect on zebrafish development.
