Published: March 2021

Root development and apoplastic transport are respectively important for
cadmium (Cd) absorption and transportation, which profoundly influence
Cd bioremediation. However, molecular mechanisms underlying the two
processes are not completely understood. In this study, we demonstrated
that auxin response factor 4 (SpARF4) from a Cd hyperaccumulator Sedum
plumbizincicola was a negative regulator for these processes. SpARF4
positively regulated by auxin was highly expressed in xylem.
Overexpression of SpARF4 significantly decreased vessel area and
declined lignin content of S. plumbizincicola. Meanwhile, less
adventitious roots were found, and lateral root development was delayed
in transgenic plants. Furthermore, ethylene production and auxin
transportation were impaired. More importantly, SpARF4 negatively
regulated Cd content of xylem saps and aerial tissues. Combining
dual-LUC reporter, Y1H and qRT-PCR assays, SpARF4 was a repressor for
two downstream genes (SpABCG14 and SpACO4) which influenced vascular
bundle development and ethylene production, respectively. PIN1, 2, 3, 7
were downregulated and slowed down local auxin accumulation rate, which
suspended root development. These results indicate that SpARF4 can
decelerate Cd transportation rate from roots to aerial parts and reduce
Cd content of aboveground tissues by delaying the root development and
decreasing vessel area.
Genome-wide evolutionary signatures of climate adaptation in spotted sea bass inhabiting different latitudinal regions

Published: March 2021

Temperature is an important climatic factor that shapes the distribution
of eurythermal species. Thermal adaptation of species is important to
both evolutionary biology and climate-change biology because it
frequently leads to latitudinal gradients of various phenotypes among
populations. Spotted sea bass (Lateolabrax maculatus) has a broad
latitudinal distribution range along the marginal seas of the Northwest
Pacific, providing an excellent teleost model for climate adaptation
studies. We generated over 8.57 million SNP loci using whole genome
re-sequencing from 100 samples collected at 14 geographic loci. We built
the phylogeographic structure and demographic history of L.
maculatus and determined sea surface temperature as the key
environmental factor and major driving force for genetic divergence and
local adaptation. We also identified distinct selective signatures and
functional genes underlying adaptive mechanisms and ecological tradeoffs
in the southernmost and northernmost populations inhabiting distinct
climatic and latitudinal zones. The results offer an opportunity to
better understand the genetic basis of the phenotypic variation in
eurythermal fishes inhabiting different climatic regions.
Does Endourological Intervention a Suitable Treatment Options in Management of Iatrogenic Thermal Ureteral Injury?
Authors: Cebeci Oguz Ozden , Özkan Tayyar Alp
Published: March 2021

Introduction This study aimed to evaluate the etiological factors and
their effects on long-term clinical outcomes in patients with iatrogenic
ureteral injury (IUI). Material and Method Twenty-seven patients who
underwent surgery because of IUI were evaluated between January 2011 and
April 2018. Patients were classified according to the time of diagnosis
and the need for reoperation after the urologic intervention. The IUI
cases detected during gynecological surgery were called ‘perioperative’
IUI, and those diagnosed late as ‘postoperative’ (delayed) IUI. The IUI
type was categorized as ‘cold transection’ due to surgical dissection or
ligation and ‘thermal injury’ if it depended on any energy-based
surgical device. Results Postoperative diagnosed cases consisted of
exclusively after laparoscopic surgery (p=.025). Patients with thermal
injury to the ureter were mostly diagnosed postoperatively (p= .021).
Patients who underwent endourological intervention, 31.25% (N = 5/16)
were diagnosed during gynecologic surgery, and 68.75% (n = 11/16) were
diagnosed postoperatively. For open reconstructive surgery, these rates
were observed to be 72.72% (n = 8/11) and 27.28% (n = 3/11),
respectively (p=.034). IUI was due to thermal injury in all patients who
developed complications after the urological intervention (p = .046),
and the first urological intervention was endoscopic double loop
stenting (p = .005). One of these patients was diagnosed in the
perioperative period and seven in the postoperatively (p = .016).
Conclusion Treatment success rates are low in patients who underwent
endourological intervention after thermal IUI. Therefore, surgical
techniques in which the traumatic ureter segment is excised should be
preferred to avoid complications. Key Words Ureter, Iatrogenic, Thermal
Injury, Iatrogenic Ureteral Injury, Endourological Intervention.

Introduction: Pyogenic granuloma is a benign lesion of unknown etiology that occurs in the skin and mucous membrane. It has been reported as a common lesion in oral cavity and less commonly in nasal cavity. Although its etiology is unclear, pyogenic granuloma is commonly associated with pregnancy, oral contraceptives and trauma. Case: A 22 year old female patient with 7 months of amenorrhoea came to ENT opd with complaints of epistaxis and swelling in left nasal cavity ultimately diagnosed as pyogenic granuloma. The patient was treated with endoscopic excision of nasal mass under general anesthesia. The management of pregnant female with such lesion was challenging, so we had to operate her. Even radiation exposure was a risk while radioimaging before surgery. Conclusion: Pyogenic granuloma is rapidly growing lesion that should be considered in the differential diagnosis of gravid patient with oral and nasal mass. Early excision of mass helped in avoidance of further complications such as fetal distress, low birth weight and reduces maternal mortality and morbidity.

Paraquat is one of the chemicals that contributes to increasing pollution Indonesia. The careless use of paraquat can increase production of ROS (Reactive Oxygen Species), resulting in damage to a wide range of vital organs and reproductive system disorders such as infertility. ROS in the body can be captured by antioxidants. Red Ginger contains high antioxidants because there are active phenolic compounds such as gingerol, shagaol, zingeron, ginggerdiol, and zingibren which are proven to protect body cells from damage caused by ROS. This study was aimed to test the effectiveness of red ginger extract (Zingiber officinale Roxb. Var. Rubrum) on the quantity and quality of sperm in male mice (Mus musculus L.) induced by paraquat dichloride.This research uses a completely randomized design and is divided into six treatment groups with each four replications: K1 as the control group (only given H2O); K2 (paraquat induced a dose of 20 mg/kg Body Weight (BW) without the administration of the test substances); K3; K4; K5 (paraquat induced a dose of 20 mg/kg Body Weight (BW) and was given a red ginger extract at a dose of consecutive succession 6 mg / ml, 12 mg / ml, 18 mg / ml) and K6 (Only given a test material the red ginger extract as much as 18 mg / ml).
