Objective: To investigate the effects of oblique nuclear chopping and nuclear extraction by binding procedure (ONCNEB) in cataract extraction.
Methods: Extracapsular cataract extraction by ONCNEB with foldable IOL implantation was performed in 86 senile cataract cases (97 eyes) by using a line-shaped cataract nuclear chopping apparatus developed by the authors.
Results: In 97 eyes treated with ONCNEB, there was posterior capsular rupture in 1 eye; anterior chamber hemorrhage in 2 eyes; elevated intraocular pressure in 6 eyes; mild corneal edema in 8 eyes which subsided within 5 days. Corrected visual acuity > or = 0.5 was obtained in 78 eyes (80.41%) one week and 91 eyes (93.81%) three months after the operation. Corrected visual acuity was > or = 1.0 in 66 eyes (68.04%) three months after the operation. Mean astigmatism one week and three months postoperatively showed not significant difference as compared with preoperative astigmatism.
Conclusion: The ONCNEB can solve the problem of implanting foldable IOL through a small incision. This procedure is relatively simple and safe.

Article Synopsis
- Waste management practices are crucial for health and the environment, especially as populations grow and natural resources become strained.
- The study investigated using crop-livestock residues and hydrated lime to stabilize urban sewage sludge through an alkalization-composting process, finding that 30% lime significantly reduced heavy metal levels and viable helminth eggs.
- The research also showed that the mixture supports earthworm survival in vermicomposting, suggesting that crop-livestock residues could be effective bulking agents for composting urban sewage sludge.
High power DC and ns-pulsed 2 MV accelerator for light ions.

High Voltage Engineering Europa BV, P.O. Box 99, 3800AB Amersfoort, The Netherlands.
High Voltage Engineering developed, built, and tested a unique 2 MV single-ended accelerator (SingletronTM) for light ions. The system combines a beam current of up to 2 mA for protons and helium in direct-current mode with nanosecond-pulsing capability. Compared to other chopper-buncher applications with Tandem accelerators, the single-ended accelerator increases the charge per bunch by about a factor of 8.

Department of Nuclear Medicine, Dr. Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India.
The aim of this study was to know the tagging efficiencies of technetium-99m labeled sulfur colloid (99mTc-SC) with different meals. Egg white sandwiches are the gold standard for gastric-emptying scan (GES); thus, an egg white omelet labeled with Tc-SC is taken as a standard meal. For evaluation, we included four meals, bread and butter, instant oatmeal, idli, and chapatti, and all meals were prepared by labeling them with Tc-SC.

Purpose: To describe a novel nucleus management technique of variable size mobile nucleus in Hypermature Morgagnian cataracts.
Methods: In this technique, under topical anesthesia, temporal tunnel incision and capsulorhexis were performed, and the capsular bag was inflated with 2% w/v hydroxypropylmethylcellulose. A chopper and phacoemulsification probe were used to consciously nudge the nucleus towards the capsular periphery (fornix) to immobilize the floating nucleus against the capsular bag recess.
