The high-grade ore was much more profitable than lower-grade ore.

Strikes are now due to take place on [...], while conductors also remain under instruction not to work any rest days or to undertake any higher-grade duties until further notice.

This chapter on high-grade pelvic prolapse by Phillip Toozs Hobson and Amallia Brair concisely reviews prevalence, risk factors, conservative and surgical management options, surgical complications and prevention.

Pelvic prolapse is an intimate condition in which education and counselling is critical to patient’s understanding, expectations and treatment satisfaction.

Surgical treatment of patients affected by high-grade high-dysplastic spondylolisthesis still represents a challenge for spine surgeons.

The additional detection rate of HSIL [high-grade squamous intraepithelial lesions] using indiscriminating ECC [abnormal endocervical curettage] was 5%. Patients with abnormal ECC were older (P < 0.001), predominantly menopausal (P = 0.001), had high-grade cytology (P = 0.032), a type 3 transformation zone (P = 0.046), and a higher proportion of HPV type 16/18 infection (P = 0.023).
